What is the GAIN switch on the back of this unit for?
New User U
on Feb 26, 2018
BEST ANSWER: It changes how much power it puts out to the head phone. You would switch it down to low gain if you are using an efficient head phone with low impedance like an ear bud and switch it up to high gain if you are using a head phone that is harder to drive. The general rule is if you have to turn the knob up over half way to get it loud enough then it is time to turn the gain switch up.

For headphones or especially earbuds that are very sensitive, it may be necessary to set the gain to the low setting so the volume isn't too loud even at a low volume setting.

It's to boost output should you need it, especially for higher impedance headphones, e.g. 600 ohm.

Thank you for your reply. I have been doing reviews for the last couple days. Today's latest technology in motherboards have built in DAC's but these DAC's do not offer the fidelity quality of sound that is required for the monolith Headset. I thought since I have this wonderful headphones could Monolith make a great dac/amp? You do .. kinda its on backorder.

BEST ANSWER: The other's that have answered are wrong. If you are using this with a Mac, the volume control in the OS is disabled.

It would depend on how hot the computer is where you stack them.
You can still use the volume control on your keyboard but that will only adjust windows volume. For more fine tuned volume control you need to adjust the knob.

You could probably stack it, it does get a little warm, you can probably turn it sideways. You can use both the volume knob and the volume on the device (PC for me). When you turn it off, it reverts to the audio on the device.

Does the volume knob also control the RCA line-out volume, or does it only change the headphone volume?
A shopper
on Mar 26, 2018
BEST ANSWER: Line out output is a fixed volume. The output is designed/intended to be fed into a pre-amplifier, AVR, integrated amp, etc for use in system with a volume control.
So, no, the volume know does not control the volume of the line out output
However, I do believe that it will control the volume of the Pre-out output.

This headphone amplifier features or has a high-current output which allows it to drive headphones with a wide range of impedances, from 16 ohms to 600 ohms. It also has have a Gain Switch with the following Instructions:
(1) High Gain (up): This setting is suitable for headphones with high impedance or low sensitivity.
(2) Low Gain (down): This setting is suitable for low impedance or high sensitivity headphones.
I also have The Stage Right Monoprice Multimedia Studio Reference Monitor Headphones 53mm (Product # 605055). It has 32 ohms and 100db sensitivity
So my question is what switch (low or high gain) is the better one to use with this headphone amplifier and The Stage Right Monitor Headphones?
Any problem if the switching done is a wrong one?
(1) High Gain (up): This setting is suitable for headphones with high impedance or low sensitivity.
(2) Low Gain (down): This setting is suitable for low impedance or high sensitivity headphones.

(Disclaimer: I'm not an expert). Your headphones won't be hard to drive, so I'd start out with the low gain setting, and only move to the high setting in the unlikely event that you need more power. The only problem with the high setting is that if you dial the volume knob up too high it will be easier to blow out your headphones (or your ears) if the gain is on high. So use low gain if it works for you..

32 ohms is pretty low. I would turn the volume rotary knob on the front panel to -90 dB(fully counter-clockwise), plug in the headphones and slowly turn clockwise towards to 0 dB. If there is enough range to suite your listening pleasure, leave it on low gain. If not try high gain using the same procedure above to suite your personal level of volume requirement.

At 32ohms, that's considered a pretty low impedance headphone. I would use the low gain setting. High gain, in my opinion would be about 120+ ohm.

It will be better than the DACs found in many bargain laptops.
Where this is nice is that it allows you to easily adjust volume with the rheostat knob, and you can switch to an alternate sound source with just a flip of a switch instead of unplugging your headphones.

I just got this and wanted to add an external media player that can play DSD files, but I see that the DAC in this only goes up to 24bit/96kHz. Do the USB-DAC specs also apply to the AUX IN or will I be able to play DSD files via a compatible media player through this and into my stereo via the AUX IN?
A shopper
on Sep 6, 2019
BEST ANSWER: No, the limits don’t apply because the AUX IN is an analog signal only via RCA jacks (red, right channel, white, left channel), so any signal being passed in to this headphone amplifier there must be already decoded from the digital domain anyway to an analog signal. If your external media player supports an analog line-out signal, this will work just fine as it will be doing the DSD decoding anyway and not the Monoprice headphone amp. Depending on your external media player’s outputs, you’ll either need a cable with a pair of RCA audio plugs on both ends or maybe a 3.5mm stereo plug for the external media player’s line out terminating in the two RCA plugs for the AUX IN on the Monoprice amp.

DSD files usually are 24bit/88.2kHz
The difference is impossible to tell. So the question here is do you have a better dac already to play through and use this only as an amplifier? If so then use it with the front switch on AUX to bypass the dac and plug into your stereo AUX in the back.
If you just have the DSD files and are playing from a PC source, keep the DAC, yes there will be a bit of conversion from your player (foobar/dophamine/or similar) but you will have the nicer dac than your onboard PC chipset.

The aux in is an analog input (RCA input on the back of the unit). So if you external media player outputs analog then you could use the aux in. You could also just convert your DSD files to any of the many PCM formats (wav, flac etc.) and then send the resulting PCM data stream to the DAC, I think most DSD player software does this automatically if they device you are using for output doesn't support DSD. Conversion from DSD to PCM is lossless.

No, AUX IN is totaly different from digital USB input and is a true analog input. If you meant headphones under "my stereo", then you can use your digital player's analog out through monoprice AUX IN and use it as a headphone amplifier.
But if we're talking about stereo speakers (passive or active), then I don't really see necessity to add another unit between your existing digital player and stereo system. Hope this helps.

With any rheostat some oxidation will occur over time or something may build up on the surface. Take your headphone jack out and quickly turn the knob from min to max several times. This has always cleared it up for me in the past.

Interesting. Just tried this, repeatedly for about 5 minutes. The noise is still there, is it considered noise floor?
No, that is not normal. I have zero noise even at max level if there is nothing playing.
Are you using it as a DAC or using the RCA inputs? It could be a short somewhere that is causing the noise and it just becomes noticeable at higher levels.

BEST ANSWER: The 1060C are 18 Ohm cans. It drives my 38 Ohm headset with clarity and ease. Notwithstanding, I primarily use it for its DAC direct out into a Class A amplifier and it sounds awesome. You're not going to do better for $70.

If your referring to the Monolith M1060C, those are 18 Ohm Impedance headphones, you should be able to run those just fine off any headphone jack...

I'm using this from a Mac Mini and when playing iTunes it works perfectly. When I try to run Audirvana or Bitperfect hi-res audio apps, however, I get nothing but noise, even when the app is just on without playing music. I've tried every adjustment I can think of in those apps and still nothing. Any ideas?

Forgot to mention... the play, and skip buttons on the Mac keyboard don't seem to work when using BitPerfect. if you run without BitPerfect, they do.

Output impedance of AAA-788 is very low! It's less than 0.05 Ohms at 1 kHz.

You will hear audio out of your speakers and headphones at the same time if both the AUX and headphones are plugged in.

Does this device have a Matrix Decoder?

BEST ANSWER: No. A Matrix decoder commonly takes a stereo output and splits it into more channels. Since this is a Stereo headphone amplifier, it only outputs a stereo signal.

I use this for my laptop and my laptop has several usb ports. Using the first one the amp gets recognized as usb audio device, the second one recognizes it as sp/dif or something like that. What is the difference in what it is recognized as, what usb port should I use?

BEST ANSWER: Audio science did an indepth review of several desktop USB DACs and compared how the PC read them as either S/PDIF or USB.
Here is the summary conclusion: As seen from pure measurement point of view, there was no case where USB was worst than S/PDIF. Indeed the reverse was true in that S/PDIF was noisier in some DACs. So the default assumption that somehow S/PDIF has some advantage over USB is simply false."
So in super summary; it really doesn't matter.

Pleasantly Surprised
I purchased the Desktop Dac/Amp as a refurbished model and after hooking it up and using it with both my Bose Companion 2 speakers and my various headphones(not too expensive), this amp is a POWERHOUSE! Being new the audiophile world and wanting a better experience I thought I should start small but just because this item is under 100$ does NOT mean it sounds that way. The build quality of the all metal body is wonderland durable, the switches are tactile and good feeling, and the main volume knob is nice with a good range of volume. For being refurbished Im pleasantly surprised and happy with my dac amp. Also with the the large amount of inputs and outputs, theres almost endless possibilities

Very nice desktop DAC/preamp
Nice Looking unit, volume knob feels great in your hand too. I've mostly used the headphone out and the line out. The headphone output noise floor is almost inaudible even with Etymotic ER-4P headphones which are very sensitive. The line out is also very nice. Only thing I would like to see changed is the obnoxious bright blue LED light.
