It doesn't need a long warm-up period... I usually let mine warm up for about 5_10 minutes before I play it. However, it sounds good right away, but seems more stable and consistent after a short warm-up...

yes. if you want better sound you will have to invest in better tubes. the Chinese tube are not that good. the rca's will come off easy if you use a tight high quality rca cable because there cheap rca female connectors. the Bluetooth connector can break very easy when tilting back. it sounds good if you got high efficient speakers. I got 92db speakers an it not loud enough for me. 94 an up speakers an it should be ok. the 10 watts per channel should be enough watts for most people if running 92db efficient speakers an up. my speakers are jbl 590 speakers. tubes do make speakers sound better than solid state amps. its a little more analog an warm. I need more power so im going to bi-amp my speakers with another mon0price tube amp. 20watts a channel an 92db will get loud enough for most people. the 10 watts a channel is proberly just as loud as the 25 watts a channel on the hybrid tube amps monoprice is selling. all tube amp will sound a lot better than a hybrid tube amp.

Yes it will but you may need some form of output control as the CD player may have too high an input and cause the amplifier to clip. Mine did and I added an inline 20dB cut to resolve the issue. With the tape player you should be able to control the output and should work fine.

Why is the Bluetooth function so much louder than the phono function?
Cullen D
on Oct 2, 2018
BEST ANSWER: Both the Bluetooth and Line inputs are much higher due to the sensitivity. I had to incorporate a 20DB reduction using a line device to overcome the output of the CD player plugged into the line input. Should be able to adjust for that on the Bluetooth device itself via the volume control. It is a problem as it will cause the amplifier to clip continuously.

Im not sure what you're trying to connect through the phono line but it is primarily for a turntable wherein the sound is picked up and transmitted through the cartridge. The sound volume and quality will differ dependent on what kind of cartridge, turntable and quality of rca cable you're using.

Its definitely louder on mine too. But I think the line in is the quietest. I usually run my turntable through a separate phono amp, fed in to the line in. Switching to the built in phone stage I didn't have to turn the volume knob up as far (to 12 o'clock position versus 1 or 2 o'clock) to get to my comfortable loud volume level. This is with 94db sensitivity speakers. By the way, the built in phono stage sounds decidedly muddy. I strongly recommend the ART DJ Pre II phono amp. And worth springing the same money again for an iPower low noise DC power supply for the DJ Pre. Remarkable improvement in already superior sound quality.

I’m not an expert on home audio systems but I do own this amplifier and have a basic understanding of how it works. While using the phono input with a turntable the built in phono tube pre-amp is being utilized. While using the BT input a solid state pre-amp is being utilized instead of the tube pre-amp. In this situation the solid state pre-amplified music from the BT input will be “louder”. This is the same case with higher end component systems too. There is nothing wrong with this situation; you’re experiencing the difference between true tube amplification and dual state amplification.

Sounds like each of these units is different in terms of input levels. My bluetooth barely makes the VU meter move (tried 2 phones and a desktop PC), but the line-in with a CD player attached pegs the VU meter at the max stop regularly, potentially damaging the amp/speakers due to clipping. Phono is somewhere in between. Very inconsistent. The question and answers above describe various level differences---they're all over the map. Quality control problem???

I got a matched quad of JJ EL 84s from Tube Depot ($50) and a set of 3 NOS GE 5670s from Antique Electronic Supply ($19) - so less shipping $60 but ~$70 total. I noticed that the orginal tubes glowed at different intensities and appeared asymetrical in a dark room, and the amp had a slight hum. The new JJs and GEs all have a similar symetrical appearance, and I hear no background noise at all. Not only does it sound better, it looks better too.
My tubes were from a place on Canada, where they actually match the triodes of the preamp tubes for an extra charge. The perfect tubes I found were JAN-GE 5670W preamp tubes and ElectroHarmonix EL84EH amp tubes, all matched with each other for an extra charge. I could not BELIEVE the amount of improvement. It is night and day, and volume ceiling is greatly increased as well. This was a 3-digit extra expense but it is immensely worth it.
My first amp had noticeable hum, then I requested a replacement. The new one came without any humming. I think it is totally by chance, but the question is how much chance you will get a Not-Humming amp. I have it around 3 months and am very happy about it.

I just got the amp and from the start noticed the hum coming from the speakers. I checked all the wiring and possible sources of interference. I even moved the unit to where it was not near any other electronics. The hum persisted. I contacted their help line and after answering their questions, they decided it was a factory defect. I’m sending the amp back for a replacement but worry it may hum too.

I have! I received my Monoprice Pure Tube Amp a couple of weeks ago. Speakers were delayed, just received 2/6. Hooked all up and HUM - significant on the Left, much less on the right. The hum is not volume or input source dependent, so it must be the tubes or the capacitors. I have a note into Monoprice customer support, waiting for them to respond.

Once and for all - I have a self powered sub running off of the pre-out. I unplugged the main speakers, and adjusted the volume on the amp, which increased/decreased the pre-out accordingly. Which is why it's called a pre-out! YES it does adjust with the volume control on the front of the amp!

I just got this device recently and I love its simple design and the retro way that it looks. I have it set up as a secondary system that I use in my workshop. It is connected to a pair of older Polk Audio speakers that I've had for years and they all sound great together, so I'm sure after the unit and tubes 'break in' a bit more, I'll appreciate the sound even more.
Unfortunately, I don't have a subwoofer connected so I can't say this with 100% certainty, but I have a long history with various stereo components and I know that typically the pre-out (pre-amplified) signal is controlled by the volume on the preamp, as external amps (and sometimes subwoofers) often do not have their own volume control.
Sorry to not be more solid with my answer, but I don't think you will be disappointed if you decide to purchase this amp.
Good luck!

According to the manual, the Pre-Out jacks are unaffected by the volume control. This seems odd to me, as many external amps do not have their own volume, but most subs do, so this would allow for more consistent bass control by setting the volume on the sub and 'forgetting' it.

I believe it does; my pre-out connects to M&K subwoofer and the power amp drives four Klipsch speakers. This setup works amazingly well at any volume level. The sub has plenty of power to handle bass but it blends into the room without drawing attention to itself

Someone bought me a pair of Sony ssc5 Bookshelf Spekers. I was looking for an intergraded amp. Yamaha 301 or emotivas TA-100. Then I came across this and always wanted to try a tube amp. So is this considered an intergraded amp? Do I need a DAC? Will the 10 Watts be enough?

BEST ANSWER: The Pure tube amp is integrated with respect of being a preamp and power amp in one unit. It does not have a DAC built in. If you need one, you could find one separately. The 10 watts of tube power is plenty for most music listening. If extreme loudness is something you want, this may not do it for you. Its great for me. I replaced the stock tubes with Wathen CryoTone tubes for the prefect audiophile sound. That doesn't mean the stock tubes are not good. The Pur Tube amp has great build quality and I enjoy the depth and clear sound. It is much more than "warm sounding."

This is a pure tube amp so it is not integrated. It has a pretty good DAC built in with the blue tooth. The 10 Watts is plenty to drive the Sony speakers. Most listening levels is only 1 true watt which is pretty loud. The sound of this amp is euphoric because it is a true tube amp. The sound is smooth and it takes out the edgy sound that digital music produces.

No dac needed and there’s plenty of power. I have this and the hybrid version. To me, the pure tube is best for attached devices like a media player or turntable whereas the hybrid is best for Bluetooth listening. Both are fantastic and powerful.

I just puchased this amp. I have not recieved it yet but am looking forward to it based on the reviews I have read. My question deals with the tube preamp section. I usually employ a separate phono stage for my turntable (an Audio Technica AT LP3 fully automatic) . I currently have an Art DJ Pre II that is solid state. If I used this in conjunction with the amps tube preamp section by utilizing the aux inputs, would I still get the warmth and depth of sound that tubes are known for, or would the Art detract from the sound since it is a solid state phono stage instead of a tube phono stage? Dumb question I know, but I thought I should ask anyway

BEST ANSWER: Sounds like you already know the answer.
Just as it warms up the bluetooth signal (we all agree that BT is the worst type of audio signal) it will warm up your solid state preamp and make your vinyl sound even better.

I have a ART DJ Pre II phono preamp that I use with this amp. It is decidedly higher quality than the built in phono pre amp. It sounds even better if you get an iPower low noise DC power supply for the DJ Pre. Every aspect of the sound improves - stereo imaging, dynamics ... I'm totally sold on power conditioning as a result of this experiment.

Good question. The ART solid state preamp shouldn't sound nearly as good as the tube preamp. The tube pre sounds natural, clear and less gritty. I would go directly into the phono inputs. I upgraded the tubes to Wathen audiophile tubes. Not cheap but definitely worth it.

I plan to use a subwoofer and connect it to the pre-outs which from my current understanding is okay. However I plan to connect my turntable to the phono input and was wondering if I will be able to just go turntable---> phono input------>speakers or if I will need to go turntable--->preamp----->phono input------>speakers? Also I was wondering if it would be possible to connect my PC to the AUX inputs as well? This will be my first time setting up something like this and I just wanted to make sure I have all the components that I will be needing.

BEST ANSWER: This amplifier has a built in phono preamp, so yes you plug the turntable directly into the phono input without the need for a separate preamp.
Also, yes you can directly plug the audio out of a PC to the aux input on the amp. Depending on your PC setup, you'll probably need a 1/8" stereo to RCA cable. I would just make sure you have the volume set to a low level on the PC when you first try it to avoid blasting. Remember, you'll have 2 volume controls.. 1 on the amp and 1 on the PC.

According to the user manual on this amplifier the pre-out does not go over the volume control but I haven’t tested that, check it out

Get yourself some 1/4" phono to rca adapters and plug the rca ends into the amplifiers outputs and then into your speakers powered 1/4" inputs. Should work fine. You could also get some balanced xlr to unbalanced rca adapters or cables and do the same thing. Only thing would be to check that the output of the amplifier is compatible with the Behringer monitors which they should be. I actually have biamped connections on my speakers and use the tube amp for the mid and high end and then use the output of the tube amp to feed a Carver amp to power the bottom end works great. Hope this helps.

You don't do it... You plug the turntable directly into the powered speakers if it produces a line-level signal... The tube amplifier has no purpose here as you described it. Otherwise, the signal would be amplified twice. Your plan is flawed.... You need a line-level signal to send to the powered speakers, not an amplified signal that would come from the Monoprice tube amplifier... What you really need is a good turntable amp that raises the turntable signal to line-level to run to your powered speakers. Hope this is helpful and clear enough to understand...

From the Klipsch website, Cornwalls have a sensitivity rating of 102dB @ 2.83V / 1m. That means with one watt of power they will make 102 decibels of sound at 1 meter. Each additional doubling of wattage should raise the sound level by one DB. At least that's the theory. So the answer is probably yes.
Anecdotally I power Klipsch Heresy IIIs with this amp nd I can make it uncomfortably loud with no problem.

I had a pair of Spendor LS3/5a. Will this amplifier drive my speaker and give a warm sound?
New User U
on Apr 19, 2020
BEST ANSWER: Hi there, In looking at the LS3/5a specifications it seems the sensitivity is only 82.5db which will likely be a bit low for this particular amplifier. Tube amps recommend a db of 90 or better to be driven easily. This amp is rated at 10w to 4ohm speakers, that'd be 5w for 8ohm speakers, your speakers are rated at 15ohm which would likely thin the power of this amp too much. Those are fantastic speakers by the look and would likely benefit from a more powerful amp. If those were mine I'd probably spend a little (considerable) bit more and go with something like the Schiit Aegir which is "beyond class A" and which will give you comparable tube sound (if not better) and enough juice to run those fantastic speakers.

The Spendors have a low sensitivity rating and are high impedence. I wouldn’t think you’d get more than about 90 db at full volume. Enough for listening level, but not much more. I ried mine with Elac floor standers with 85 db efficiency and was underwhelmed. My Tektons are 95 db and can drive them to about 95 db. The amp does have a warm sound. Slight simbilance with female voices. Overall, a nice amp. Hope this helps.

BEST ANSWER: I don't use this amp to power speakers, I use it to power a set of Stax electrostatic headphones. Which it does very well. The Monoprice site states that the pre-out is intended to be used with a subwoofer. Since it's a pre-out and the amp is only a 10 watt amp, it would have to be a powered subwoofer.

Yes that is exactly what I am using the pre-outs for. I do have a Y connector which can be used at either the amp pre-outs or the sub in as needed. My sub is the definitive 2000 which turns on when a signal is detected

Does anyone have one without HUM? Mine has a lot. I like the warm and sweet sound. Should I try another one?

BEST ANSWER: This seems to be a common problem, but I've never experienced it myself. I did swap out all the tubes, bought a better AC cord, and have it plugged into an AC line conditioner.

Don't live with the HUM! Replace the front 3 pre amp tubes with GE JAN (Joint Army Navy) 5670w tubes. They are smaller but, seem to be the go to tubes. Sounds great, no hum.

I bought this amp in Feb. 2021, had hum too. I replaced all 6N3 tubes with new ones, and hum was gone, no other changes were made.
