Our engineers and audio experts have spent countless hours listening to and comparing various components until we were satisfied we had found models that fit our demanding standards.

    Style: Featuring a polished piano black case and a brushed aluminum face, the exposed tubes and lighted VU meter combine to give this amp a sexy appearance that is at once both classic and futuristic.

    Versatile: Enjoy your music the way you want! Use the stereo RCA jacks to connect directly to a CD player or use the Bluetooth® v4.0 radio to connect wirelessly with your phone.

    25-Watt Stereo Hybrid Tube Amp

    Because of its lossy nature, digital music can often lose some of the depth and warmth that give it life. Additionally, wireless streaming adds an additional layer of digital compression, which can further degrade the audio quality. The addition of the tube preamplifier stage adds back some of the warmth and richness, breathing new life into your digital music.

    In that most consumer speakers are rated at 8 ohms, is this actually 7.5 watts RMS per channel?
    Stephen B R on Jun 5, 2017
    BEST ANSWER: yup you are correct. only 7.5watts each at 8ohms. but dont be mislead, that is still plenty powerful for a mid sized room. i have them connected to a pair of floorstanding speakers in my bedroom, and it doesnt sound at all underpowered.
    I own this amp and although quite pleased with it, it has only allowed me to sync with my first android phone. I have a second one and my wife has apple phones, none of which will pick up the Bluetooth signal from the unit. Can anyone help sort this out? This is only about the model 13194 - 25 watt stereo hybrid Tube Amp
    Keith M on Mar 30, 2017
    BEST ANSWER: I'm sorry to hear that, please feel free to contact us at tech@monoprice.com with a detailed summary of the issue you are experiencing and our knowledgeable Technical Support staff would be more than happy to assist. Thank you
    Can this amp go between a laptop computer and desktop speakers? What cables do I use? Thanks. David
    A shopper on Nov 21, 2016
    BEST ANSWER: You can plug you laptop to this Tube amplifier. You will need passive (non-amplified) speaker. You desktop speaker are most likely powered. Take a look at the Stereo Tube Headphone Amp with 24-bit/96kHz USB DAC, Bluetooth, and Preamp Out. You can use with analog connections or USB from the laptop. This has a Line Level output that will work with your powered desktop speakers.
    What is the power output of the headphone connection?
    Brendan W on Jan 18, 2017
    BEST ANSWER: Will drive HE-400 magnetics.
    does this amp connect to chromecast audio?
    A shopper on Dec 29, 2016
    BEST ANSWER: Chromecast Audio(CA) is a audio-only device versus Chromecast(CV), which is a video device. And yes, it will support the Chromecast Audio(CA) but note that the Chromecast Audio ships only with a 3.5mm cable and you will need to get a RCA Y cable seperately.
    Does this have AM/FM? Or does Mono Price plan to bring a unit out that has AM/FM? Or a easy way to add it.
    Bryan L on Nov 25, 2016
    BEST ANSWER: Unfortunately this unit will not include a built-in AM/FM Tuner. You will need to have a separate tuner which can be connected via the RCA line-in port.
    Mine came with the tubes installed and not in separate boxes. Setup manual says the tubes are not pre-installed and that I'm supposed to install them. Anybody experience differently? Did I get a used one?
    Michael K on Dec 27, 2016
    BEST ANSWER: Thank you for all of your great responses. We had some shipping issues with DOA tubes. We were going to ship with tubes uninstalled then discovered a better socket for the tubes. We chose to keep your experience as simple as possible. We kept the manual the same because it does give important info on replacing your tubes when they go bad which should be about 2-4 years.
    Do I need a preamp between this and my turntable?
    A shopper on Dec 10, 2016
    BEST ANSWER: Yes you do, and make sure to ground things appropriately.
    I have no existing system. I think I need a CD player and speakers?
    A shopper on Apr 18, 2017
    BEST ANSWER: You will need some speakers. Depending on how big of an area you are filling. This amp is pretty low power, so some bookshelf 3-way will work Monoprice has some nice choices that are reasonable. It has inputs on the rear, that wil accommodate a CD player or turntable. The great thing about this amp, it has Bluetooth! Hope this helps!
    I'd like to connect this to a Subwoofer with line-level inputs. Any way to do that? Hacks?
    A shopper on Feb 12, 2017
    BEST ANSWER: Just run the L/R speaker outs to the corresponding lines in on your sub. I have a similar setup with a pair of bookshelf speakers and a small sub, and it adds that extra something on the low end.
    Could I efficiently drive Bose 901 iv 70s speakers with this.
    Will it accept Bose eq??
    A shopper on Jan 2, 2018
    BEST ANSWER: Not enough power for the 901’s, don’t even try. The equalizer is not the issue; rather the 901’s are notoriously power-hungry. 75 Watts rms per channel minimum to drive them...
    are these tube amps bridgeable?
    New User U on Nov 23, 2017
    BEST ANSWER: Not having access to the schematic, I would venture to say that, no, it is not possible to bridge the two channels to drive one speaker load and in the process increase the power output. If it had that capability, there would be a dedicated switch or movable jumpers to alter the signal path.
    To connect this amplifier with a pair of speakers, would you need two pair of the speaker wires sold here? The speaker wire I see here comes in a pair of red and black connectors. I would need to buy two of that item, correct?
    Rodney G on Nov 23, 2017
    BEST ANSWER: You need a left pair and a right pair. Each has two wires for positive (red) and negative (black). Good quality lamp cord works well.
    Can this amp go into mono mode where I can mono block 2 ? One for each speaker?
    A shopper on Mar 25, 2017
    BEST ANSWER: I think that you are trying to describe 'bridging' the Left and Right Channels to drive one speaker load. Not having access to the schematic, I would venture to say that, no, it is not possible to bridge the two channels to drive one speaker load and in the process increase the power output. If it had that capability, there would be a dedicated switch or movable jumpers to alter the signal path.
    Can you. Connect wired speakers?
    A shopper on Jan 9, 2017
    BEST ANSWER: Yes this is designed to use wired speakers to listen to the music. The BT is for receiving music and not for sending it elsewhere.
    Could you recommend any subwoofer models to connect to this system?
    A shopper on Dec 26, 2016
    BEST ANSWER: You will need a subwoofer that accepts speaker-level inputs and has its own cross-over (unless you plan to use a more complicated setup with something like a line-level splitter and external cross-over). You simply run speaker cables to the sub and then from the sub to the mains. Monoprice's subs are an option. See: http://www.monoprice.com/product?p_id=9723 I'm using a Definitive Technology sub with NHT Superzeros using the speaker-level cross-over built in to the sub, and it sounds great.
    can I use this with wireless bluetooth earphones ?
    A shopper on Dec 5, 2016
    BEST ANSWER: The Bluetooth is an input not an output. Your headphones would need a transmitter plugged into the headphone jack to work or they would just sync with your source
    How is the noise floor on either the 25 or 50 watt? Can any interference be heard from bluetooth or other wireless signals?
    A shopper on Sep 25, 2017
    BEST ANSWER: Noise floor not noticeable to me. When I am using the Bluetooth on the amp, no other issues and have several wireless ipads etc. going. Signal on the Bluetooth is clear with no interferance.
    I connected this amp to my desktop using 1/8" to RCA cable. When I do that I get a lot of computer noise. I get buzzing when I move my mouse and when the screen updates, I get buzz corresponding to amount of screen change. Anyone else having this problem and what would be a good solution for that?
    John K on Aug 6, 2017
    BEST ANSWER: You are getting 'ground loop' noise form your computer's switching power supply. Now that Radio Shack is history, you might try a big box audio/appliance store whose auto installation department might carry an 'audio isolation transformer'. This device transfers the audio signal between your computer's line output while isolating the GROUND connection between the noisy computer power supply and the power supply of this amplifier. The computer is the culprit since you described the noise mimics mouse movement. Also try Parts Express or MCM Electronics in their auto sound products.
    on the 15W, the bluetooth input is dramatically lower (25%-ish volume drop). how's the BT input level on this one? even with the line-in?
    Hunter W on Jun 1, 2017
    BEST ANSWER: On my unit, I don't notice any perceivable volume changes between inputs.
    Where would I get extra tubes? Walgreens?
    A shopper on Dec 27, 2016
    BEST ANSWER: If you were to need to change the tubes, I have seen websites that specialize in tubes. Hit google up. There is a whole specialty niche , people refurbishing/using tube audio equipment.
    Can I use it to drive Lowther loudspeaker tp1 mp3a?
    is it for 110 and 220 watt+
    New User U on Dec 30, 2017
    BEST ANSWER: I'm not familiar with the speakers you have in mind, but, I see Lowther says they are leaders in speakers that include horns and that this is a folded horn style. That should translate into efficient speakers that don't require a lot of power and from the specs on their website:

    Internal layout of TP1
    Power Rating:10 to 100 watts
    Drive Unit:Lowther EX4 (Other drive units to choice)
    Impedance (nominally):8 ohms
    Frequency Response:40Hz to 22,000Hz ±3db

    I'd say it would work, but, you might do better with the next model up that has a little more power. I am using them with some older very small infinity (non-horn) bookshelf speakers and they work good and don't distort, but, sometimes I would like a little more volume which I think more power would provide, although I might blow the speakers.

    Someone else may be more knowledgeable though.
    Does a record player need a preamp with this?
    A shopper on Dec 26, 2017
    Which monoprice speakers would the 25W tube amp hybrid work well with? Can it power the 13778 (select 4in) and the 13706 (select 5.25in) speakers well? What about the retro 4 in bookshelf?
    Ramon M on Sep 19, 2017

    Premium 5.25 Inch 2-Way Bookshelf Speakers (Pair) - Black Finish
    Premium 5.25 Inch 2-Way Bookshelf Speakers (Pair) - Black Finish
    Select 4-Inch 2-Way Bookshelf Speakers (Pair), Black Finish

    Retro Bookshelf Speakers 4-inch 2-way, Black (pair)
    Retro Bookshelf Speakers 4-inch 2-way, Black (pair)
    BEST ANSWER: Thank you for your interest in this tube audio system. The 5.25" Select's will give best bass performance, the Retro's are the best overall sounding, and the 4" Select's are the lowest priced. All three will work very well with this amp. The choice is up to you, your style, and your budget.
    Is it compatible with BOSE M2 MusicMonitor? Is it a Tube Amp or a PreAmp?
    A shopper on Jul 5, 2017
    BEST ANSWER: This is a power amplify, no preamp stage. This has only speak out. If your Boss M2 has speaker input, it will work.
    Does this have a DAC?
    A shopper on Jun 10, 2017
    BEST ANSWER: It must have one to interpret the bluetooth signal but there are no other types of digital connection so it would not be able to use other digital sources without a stand alone DAC.
    Can this be used as a pre-amp, coming out of the headphone jack to a power amplifier?
    Stephen B R on Jun 5, 2017
    BEST ANSWER: I don't see why it would not work, I have it hooked up to my aport express which puts out a very low voltage and it plays my iTunes songs on large speakers
    Can a electronic keyboard headphone output connect to this amp with the right cable?
    A shopper on Jun 3, 2017
    BEST ANSWER: I do not see why not. The "CD" input is a standard RCA audio input.
    I like to use this amplifier as center channel mono amplifier for my vintage stereo system to drive a center speaker. Can I set this amplifier in mono mode?/thanks
    New User U on May 18, 2017
    BEST ANSWER: Hi. There is no mono setting on the amp but you can play mono music on it. You may want to consider getting the 50w instead because 25w may not be enough to power your speakers adequately.
    I would like to use this as a headphone amp only. If I put an RCA analog cable on the REC out outputs on my current integrated amplifier, and plug the other end in the RCA analog inputs of this Monoprice tube amp, will it work?
    My current headphone amp is plugged in this way.
    Daniel H on May 12, 2017
    BEST ANSWER: Thank you for your question. That would work just fine. As you mentioned you would just plug into the RCA inputs on the Tube Amp and switch it to the CD input on the front of the unit.

    Great Sound - Glimpse of Tube Heaven
    This review is written from the perspective of an audio enthusiast who has had significant experience with tubed equipment over the years. It is considered from the perspective of its performance within its price point as an "integrated" amp that provides control functions in a unit with a tubed driver stage and solid state (operational amps?) output - therefore "hybrid" designation. Context for this review was 16 ohm speakers in a desktop - office system driven by Windows-based machine through a professional audio interface - and Bluetooth streamed from an iPhone 6.

    First the negatives: The "25 watts" is "peak power" output. This specification is rarely, if ever, used by audio component manufacturers. If you look closely the "RMS" output it is "15 watts" into "a 4 ohm" load.

    Many speakers available present an 8 ohm load, and most amplifier companies will express "RMS" power into 8 ohms which divides the actual RMS power of this amp (rated into 4 ohms at which time it reaches its stated level of distortion) by half or approximately 7-8 watts - if you were to compare it to other amps using a RMS into 8 ohm load. Now, that being said, its the first watt that is important and this unit does that very well. 7-8 watts for a desktop, office, bedroom or dorm-room system is more than enough.

    Secondly, the power switch is clunky and mechanically scratchy when actuated. It does not inspire confidence in terms of long-term reliability. This "problem" stands out ironically because the rotary knobs are wonderfully silky, with nice resistance and not at all what I would expect at this low price point - in a good way.

    Finally, like others, I could not completely remove the protective plastic from the "vu meter" there is some residual still stuck under the bezel that I won't attempt to remove for fear of causing more harm than good. This is a petty aggravation.

    Now for the reason to buy this unit: the sound! Used within limits, it renders mid-range (voice, acoustic guitar, etc.) with amazing detail, dynamics and tone color. I'm listening to the amazing guitarist Michael Hedges (streamed online music service 16bit-44.1khz) while I type. The qualities of his amplified and effects-affected Martin come through clearly with good rhythmic drive and the delicate characteristic tone "color" associated with his Martin. Truly amazing for this price point!

    Extreme highs and lows do not hold up quite as well, but I ascribe to the belief of "get the mid-range right and everything else will fall into place". Do not expect headbanging, Skrillex or Metallica to hold up well. Overdirive the unit and it flattens out losing much of its tone color and dynamics.

    Headphone listening came with the same positive benefits mentioned earlier.

    I did limited listening Bluetooth with mixed results. (iPhones earlier than 6s do not take full advantage of the AptX wireless streaming, so I cannot fairly comment.) Some music sound great as if coming right off the digital interface other music sounded very limited and grainy like most MP3 or MP4A out of the box where cymbals sound like peas rolling in a tin can - sorry. I think its more of a "format" problem.

    Overall, a well designed execution. Monoprice does not need to inflate the power spec, this unit sounds absolutely wonderful when operated within its limits.

    This product is musical, amazing at this price point and highly recommended as a desktop, bedroom, dorm-room music player.

    PROS: Sound quality - a glimpse of tube heaven

    Affordable and easy to find replacement tubes

    Great "desktop" and headphone amplifier

    Amazing value

    CONS: "25 watt" naming is modestly deceptive

    Clunky power switch

    Plastic protective covering on "VU METER" impossible to completely remove

    Volume does not completely mute signal through CD source
    November 18, 2015
    Refurb had to be kicked back
    Looks good, has a good girth and streaming Pandora via the BT was surprisingly satisfying. I paired it with a set of Wharferdale Diamond 7.1 and it was a good match. Interesting to note, streaming via my iPad produced a fuller playback than using my Note 3 both with Pandora.

    The bad, in ascending order:
    My refurb unit had an occasional light hum, but it could only be heard if you weren't playing something. Non-issue for me, but for some, this could be a problem.
    Clips at half volume. But this was setup for a bedroom, so the output was acceptable.
    The right channel kept going out. I tried different speaker cables and cleaning the terminals, but no joy

    I could've sworn that the unit had a 30 day, money back guarantee, but MonoPrice is only offering me a store credit.

    PROS: If not for the failure of the right channel, I would've been singing the praises of this amp

    CONS: Clipping at half volume and failure of the right channel
    April 22, 2016
    Sorely Disappointed
    My husband was really looking forward to this for his birthday and when it arrived the amp would make cracking and popping noises when playing music. We requested a replacement and when we finally received that one it had the exact same problem. So either the merchandise is being manufactured poorly or they sent the same one back. Either way, I'm not buying from them again.
    January 17, 2016
    Six months and DEAD
    Smoke and burning smell came out of nowhere 0ne night resulting one the of the speaker terminals not working - all in just 6 months of very little use (a few hours a week on average). Before this, low pitch interference can be heard from the speakers, but I accepted / got use to it. It was not very noticeable when volume was louder and when the bluetooth paring device (my phone) was closer standing next to tube amp. I have send an email to Monoprice asking for warranty but have not got a response. Don't recommend it because, in my experience, the speaker terminal problem is common.

    PROS: Sound good, simple and easy to pair up. Doesn't take up much space and look good.

    CONS: Broke in 6 months of little use. No more sound from one of the speaker channel.
    July 2, 2016
    Worked great at first, losing luster recently
    Bought the unit in mid November of 2015. Easy to set up my 2015 Mac Pro connected via bluetooth immediately. Made my KLH speakers sound the best they had in years. Was really happy with the purchase.

    However - of course there is a however - in the last month problems have started to develop with the amp. The bluetooth will stutter after an hour or so of use. Mostly it just drops audio for a second at a frequency of around two minutes, but every now and then it disconnects completely then reconnects to the Mac Pro with a "your phone is connected" message. Turning the amp off for a few minutes then back on will make the problem go away... for an hour or so. I've turned off the BT on my phone and tablet, to no avail.

    To get around this I plugged in a cable from the Mac Pro to the CD inputs on the back of the amp. No good within seconds a background hum starts that builds in volume past any comfort levels. This is the same cable and sound port on my Mac I used for my old amp, so I don't think that's the problem.

    Then the power button fell off.

    Based on other reviews it appears the unit quality is hit and miss. Mine missed.

    PROS: Full bodied sound

    CONS: Bluetooth problems, growing background hum for cabled input, quality of parts
    February 6, 2016
    A True Bargain
    When I unpacked it I was amazed at the build quality and looks. It came well packed with tubes in place. Now since this is a hybrid I didn't expect it to fare too well against my tube amps given the low price.. Boy was I surprised.. Nice warm tube-ish sound with a huge soundstage. This is going to be a tube roller's delight.

    PROS: - Sound Quality

    - Solid build, quality construction

    - Attractive looks

    CONS: - Side panels fingerprint easiy
    November 2, 2015
    Awesome sound & beautiful looks
    This is a great little amp. It's gorgeous, with it's glossy black case, brushed metal faceplate, and warm glowy tubes and VU meter. And it sounds lovely. I haven't really cranked it up hard yet, but it does an admirable job of driving the pair of Fluance SX6 speakers on my desk. I can hear a bit of a hum through my speakers when nothing is playing (and I'm powering this through my big UPS, so it's not a bad ground). I just shut it off if I'm not listening to anything anyway, so no big deal.

    Sounds awesome, looks to match. If you're looking at this, it's because you want one just buy it and start enjoying your music again.

    PROS: warm tube sound, great looks, well packaged, incredible value, simple Bluetooth connectivity.

    CONS: gloss black shell can show finger prints (so stop touching it!)

    tubes get warm (as expected so let the thing breath and don't touch em!)

    has a bit of a hum

    Surprisingly good still connected to main speakers for a month now
    This is a beautiful little amp and is extremely well packaged with thick custom foam pieces and double-wall cardboard. Right out of the box, I had it hooked up to my Pioneer Andrew Jones LR22 bookshelf speakers, which seemed a good match. I enjoyed it that was for a few days. Next I put it in place of my main amp and tried my Koss CM1030 4-ways, which are 94dB sensitivity and 5 ohms nominal. This little amp will drive them cleanly to upper-90 dB peaks and 90dB average levels. Bass control is very good and it has a definite tube sound. So far, it has stayed in my main system since as it is fun to listen to. I found some Russian military 6P15 and 6N2s and rolled them in place of the stock Shuguang tubes. It's a bit quieter now and airier, but the sound was quite good out of the box. For the money, this is a fun amp and worth every cent. I can enjoy tube sound without putting hours on an expensive set of quad KT88s in my main amp. I have tried Blue tooth and direct in and the BT works quite well with good sound and range, very near CD quality. The BT certainly won't diminish any MP3 listening. With a 30 day return on this amp, if you are on the fence, just give it a try. It seems like some of the QC problems with parts have been fixed since it was introduced, so it seems that Monoprice listens to customers and also handles returns easilywhich is good considering that any tube gear can take a hit in shipping.

    PROS: Compact
    Low power consumption
    Tube sonics
    Bluetooth convenience
    More power than with small-signal tubes alone
    Fairly portable

    CONS: Works most efficiently with ~4 ohm speakers
    The "ray gun" rings around the tubes may not be for everyone
    Speaker connections don't give much room

    What has been missing my whole life...
    I saw similar hybrid amps a couple of years ago, and thought they looked good, but wasn't sure if they were going to be just a passing fad, and resisted the urge to buy another piece of audio equipment. I've been noticing I've been listen to a lot less music lately, just because digital music just doesn't sound that great. Love the convenience of bluetooth, but music just doesn't sound like live music any more. I'm redecorating my cabin, which often becomes the dumping ground for a lot of my spare stuff. I use studio monitors / external computer interface in my house and office, and moved my hpome stereo system there. I decided to upgrade an d pulled the trigger on a new amp. FIrst of all, this amp looks really great. Love the warm light lights of the tubes, so pleasing to look at compared to LED. The sound is spectacular. Compared to my Denon amp, this thing is completely, undeniably, better! Music sounds like music again. Wow. I'm pretty busy, but just wanted to wanted to share my experience for others out there who may have lost enthusiasm about music.

    I use a cable from my laptop whenever I can, and bluetooth from phone works pretty well, though not as impressive. However, shockingly better than phone going through bluetooth to a standard amp.

    Words of caution though: 20 amps per channel is not a huge amount of power, and i have it turned up almost all the way. My speakers must be about 89 dB sensitivity, and I would be cautious if yours are less than that. Doesn't seem to clip at the top end though.

    Hope Second Time is the Charm
    Arrived the day after Thanksgiving. Set it up to discover that the right channel was dead, along with one of the vacuum tubes. Two of the remaining three tubes weren't functioning at peak levels, either.

    Contacted Monoprice and they were quick to issue an RMA and the bad unit will go back on Monday. Hopefully, a replacement unit will ship soon. I'm looking forward to connecting this to my Bose 141 speakers.

    I'm giving a 10-star review because of Monoprice customer service. Outstanding, so far. Once I get a functioning amp, I'll review it based on performance.

    PROS: Looks nice, but don't know about the audio quality yet. Monoprice was quick to do an RMA. So I hope to have a replacement amp soon.

    CONS: Arrived damaged.
