    Sound Quality

    Sound Quality: Life is too short for audio products that don't sound great! We believe that the whole point of listening to music is to hear it as the artist intended. 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.

    Bluetooth® audio for grownups. Listen to music like you care about it.

    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.

    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.
    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: If your turntable doesn't have one built in yes. Newer turntables can have a phono amp built it. If not you will need a separate phono amp to play it on most newer systems that don't have a built in phono amp. This should not be confused with a turntable with a USB output for a computer. Those wounds not be compatible with this amp unless you Bluetooth from your computer to the amp. I will say that the Bluetooth on the amp works very nicely it streams from phone computer and DAC well.
    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: there is no Subwoofer line level output from this AMP, you can line signal converter , covert speaker output to line output converter, such as this one from Bestbuy. dot com

    Metra - Two Channel Line Output Converter
    Model: TC-LOC2SKU: 1265702
    I ihope this help! good luck
    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.
    Where would I get extra tubes? Walgreens?
    A shopper on Dec 27, 2016
    BEST ANSWER: These tubes are for the pre-amp only. The power amp is traditional transistor based. Pre-amp tubes last forever (as opposed to what they write in the product manual.) Power amp tubes need to be changed with some frequency.
    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
    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: 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.
    What is the power output of the headphone connection?
    Brendan W on Jan 18, 2017
    BEST ANSWER: Will drive HE-400 magnetics.
    Can I cable out from the headphone jack to a higher power amplifier?
    Stephen B R on Jan 8, 2017
    BEST ANSWER: It would depend on what you want to use the output for. If you want to feed it directly into a microphone input, I wouldn't do it. If you plan on sending it to a "line in" input, then you should be okay.
    does this amp connect to chromecast audio?
    A shopper on Dec 29, 2016
    BEST ANSWER: If you want to separate the video from the audio, as in streaming the video to a TV and the audio to a stereo, you'll need an audio extractor, such as the Blackbird™ 4K Series 2-channel HDMI® Audio Extractor, such as the Monoprice item 13349.

    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

    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.

    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

    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

    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.

    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

    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.
    November 29, 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

    A great looking amplifier with an interesting mix of tube pre-amp with a 25w solid state amp
    The Monoprice Stereo Hybrid Tube Amp is a great looking amplifier with an interesting mix of tube pre-amp with a 25w solid state amp. It delivers a warm rich tone that is a throwback to older full tube amps and to my ears sounds wonderful. The built-in Bluetooth 4.0 was a pleasant surprise and while I did hear a tiny bit of low end clipping when streaming, it was on par with all other Bluetooth streaming I have used. It also has one RCA input on the back for your computer or other component. (my record player sound great on this)

    The Monoprice Select 2-way 4" bookshelf speakers that come with this package definitely sound good work well with this combo. I really like the composite material they are made from as the finish looks great. The included 10ft braided speaker cables are the nicest I have ever used and look great.

    I tried this with all kinds of music and to my ear I liked it with everything but classical. Rock and jazz sounded particularly awesome to me, but like with any audio my results are highly subjective to my preferences in sound.

    Would love to see in v2

    - Only 1 set of RCA inputs (would like to have seen 2)

    - Would be nice if it supported 2.1 for a little more kick

    At then end of the day, this will be the primary source of amplification for the sound on my computer moving forward and I highly recommend it. Just remember this isn't an amp that I would recommend to edit audio with due to the additional warmth you get from the tube amps.

    NOTE: This unit was provided for review by Monoprice

    PROS: - Nice rich warm sound

    - Nice mix between modern and retro look

    - Solidly built

    - Bluetooth 4.0

    - Quality RCA terminals

    - Braiding on speaker cables + quality connectors

    CONS: Cons

    - Size is a little big due to tubes

    - Glossy plastic finger prints easily
