When using USB input, why does unit always display 48KHz regardless of source?
A shopper
on May 29, 2019
BEST ANSWER: Not sure about Macs, but for Windows, make sure to install the provided XMOS driver from the product page, check that you have the latest firmware, and most importantly, in the Device Properties window Advanced tab, make sure to enable both boxes regarding Exclusive Mode so WASAPI compatible software can enforce the correct output to match the source. And some apps (Tidal) need you to dig into their settings to enable using exclusive mode.

The amp/dac can output at least 192khz I believe. I had the same issue so I had to go to sounds-> thx aaa amp/dac-> right click-> properties-> then you can select the bitrate/samplerate you want your PC to output to the amp/dac. When I'm outputting via Tidal it displays 192khz and outputting via foobar will the sample rate of the file matches the display. Also you may need to update the firmware of the amp/dac if you're still having issues.

On the HOME screen, there is a persistent "H" just to the right of the sound DB level. What does it mean?
A shopper
on Feb 9, 2021
BEST ANSWER: It indicates the output mode you are currently on. 'H' means "Headphone" and refers to the XLR or 1/4" jack on the front of the unit, whereas the other mode 'L' means "Line-Out", the red and white aux jacks at the back of the unit. You can switch between the two modes in the settings menu.

My unit came with firmware 1.04 pre-installed. But the latest firmware listed on the product page is 1.03. should I update to that?
A shopper
on Oct 18, 2019
BEST ANSWER: I would not "update" it if it came with a higher version. Mine came with 1.01 and I did the update.
According to the official changelogs posted, all 1.03 does is fix an issue with the phase of the back outputs.
As 1.04 is higher than that, I would expect it to include those fixes.

The DT 1990 Pro offer only single ended connection. The spec sheet says the amp is capable of 150mW into 300 Ohms, and 290mW into 150 Ohms. So let's just take 150mW as a minimum it will be able to deliver into 250 Ohms of the DT 1990 Pro. The headphone will produce an SPL of 102dB (which is VERY loud) given only 1mW of power. This would give you nearly 124dB of SPL with the amp on full power. And general health advice says, that you should not listen to anything that loud for more than a few seconds if you don't wish to suffer permanent hearing loss. So yeah, plenty power here. I myself use the HD600 with it, wich is 300 Ohms and has a similar efficiency to the Beyer headphone, and it sounds very good, no distortion or anything. So go for it. And read up on power ratings and the dB (decibel) scale to make your life easier in the future.

Are there gain or impedance levels on this? If so how do you switch between them? I do not see it in the menu settings or the manual.
Michael G
on Jul 30, 2019
BEST ANSWER: No there are not gain settings. I have read some report there is slight noise with very sensitive IEMs; some have solved this grounding the case; some with impedance cables - which largely provide the same as a gain switch. I use mine with full-size headphones of mixed sensitives as well as a pre-amp and it is black as black for me but I don't have anything extremely sensitive.

I don't own LCD-2 headphones, but this amp has plenty of power, especially if you used the balanced output. But for 99% of headphones you should be fine with the single ended output. It'll power the LCD-2s just fine.
This is a very transparent DAC and amp. So it will just provide clean power to your headphones—some might say it leans a little on the analytical side, but from my limited experience (I've only owned a couple cheaper amps like Schiit Vali) it just sounds like a wire with volume knob. It won't add warmth like a tube amp, and it won't sound cold or etched like some solid state amps.
I'd recommend reading some reviews on the Jotenheim 2. I don't own this amp so I can't really say exactly how it sounds. From my limited experience with Schiit and things I've read/heard about their products in general is that they're good for the money. In all likelihood, both amps should power LCD-2 just fine and sound good, so I would recommend focusing on what features you need and get the one that fits your situation better. If both amps satisfy the features you need, I'd then just get the one that you like the looks of more, or can get for cheaper.

After scouring the internet for compatible xmos drivers for ASIO DSD playback, I found Thesycon trial drivers that worked, but after 30 min it starts playing a test tone every min. The only way I can stream using ASIO through the DAC is using Asio4All. It fakes a driver so your player can grab it for ASIO output. This is how I get DSD streaming, but it only works for DSD64, but not 128, probably because of bandwidth constraints.
So the standard Windows USB driver works for all PCM by DirectSound, but switching output to WASAPI doesn't properly send DSD.. Someone correct me if I'm wrong, but as far as i can tell, WASAPI and ASIO outputs need dedicated Drivers provided by the manufacturer to stream DSD to the DAC.

Dirac sensaround blew me away by how good it is. It definitely is not a gimmick. It makes headphones transparent, you don’t hear left and right, just the music. Closed headphones sound better than open. My open Elears sounds the best with sensaround. It just makes them sound effortless. The biggest improvement was on my IMR R1’s, it made them sound like speakers.

I’m seeing a balanced cable on Amazon for the 1060C. In fact, there are both XLR and TRRS cables shown. That may do the trick.

Yes. You can bypass it. However, when I tried to use it with the SMSL SU8, (which sounded amazing with my Jotunheim) it sounded VERY subpar compared to the internal DAC already in the 788. I don’t know if it was synergy or the chips being that much better but since I’ve tried this, I’ve only used the internal DAC. What DAC would you pair with this?

I was going to pair it with my own SMSL SU8 as well! Was planning of pairing the SU8 with the Massdrop 789 but I missed out on the drop AGAIN. So I thought I might as well get this Monoprice instead of waiting forever for the 789. So wouldn't recommend pairing the SU8 with the Monoprice correct? Just use the Monoprice on its own?

Absolutely. You can give it a shot as well when it arrives. I gave it another shot this morning, just to double check. Strongly recommend just running the 788 on it’s own. MUCH MUCH better! Lol

Unfortunately no, but to me it is not a big deal, just don't scroll the volume to fast. I asked a question to Monoprice regarding adding a 20hz region in the PEQ in a future firmware update. Hopefully they will add this along with fixing the speed of the volume control.

If you turn it normally it works fine, but it's not logarithmic so to make a large change you have to turn it a lot and going fast it lags and keeps going. In my opinion it's the one and only software issue.

For speakers I would recommend just using the rca line outs on the back of the unit. Keep in mind this unit is not meant for powering speakers, so make sure you only use this for outputting music to "powered" speakers.

Yes. The rear RCA out connections on the back of the amp is the "line" output in the settings. The front xlr and 1/4" jack are the "headphone" output in the settings. I have my speakers connected to the rear RCA out and my headphones connected to the front xlr port. I switch between the 2 depending on which one I want to use.

BEST ANSWER: The control panel permits the amplifier output (variable) to be directed either to i) the XLR4 and 1/4" TRS, or ii) to the RCA outputs on the back. In either case it is variable level controlled by the volume knob, so it can function as a preamp for speakers.

Can we pass SACD DSD to this unit? I was under the impression that this can only be passed via HDMI.
Timothy H
on Nov 22, 2017
BEST ANSWER: Yes and no. You cannot hook up a SACD player to the unit since it does not have an HDMI input. However, anymore the DSD files, formerly only found on SACD's, are available as Hi-rez downloads from quite a few sites and some people have even gone to the considerable trouble of ripping their SACD's, so they have the files on a computer. Once you have the DSD files on a computer, you can play them on this unit via the USB type B input, assuming your player software supports the playing of DSD files (JRiver, for example). Also, if this unit supports DSD over DoP, you could probably use the coaxial digital input, but it is not stated if this unit allows that. This usually only works for 2.8 Mhz DSD files, not the 2X or 4X resolution files as coaxial doesn't have the bandwidth for that.

You can hook up any SACD player with analogue outputs to the amp and you will have DSD playback. However, this setup bypasses the DAC in the amp so the listener will be dependent upon the player’s DAC for SACD playback.

Awesome product easily worth $500.
I freaking love this thing. Clean af sound and doesn't get hot. Actually don't have anything negative to say other than where the controls are placed but you get used to it. Or maybe kinda sucks you cant switch quickly between line out and headphones, you have to go through the menu to do it. Anyway, watch Zeos review on YouTube..he's 100% correct. Go buy now.

I?m very pleased with the Monolith. Primarily I use Focal Elegia headphones with it and have had great results. The amplifier drives other headphones such as my Audeze LCDs well also. If I had a complaint it would be the way adjustments are made to the EQ. A little too much consolidation of functions into one control, I think. But, once set, I don?t tend to tweak settings so it isn?t a day-to-day issue for me. Overall, good job!

Tidal has done a great job with their masters streaming and i am swapping hifiman 400i and dan clark flow x. the 400i seem to be better, but they are balanced cable. i have a balanced cable coming today for the flow x. i think this will improve the cans. overall i like the unit. but i am going for the drop 789 later and i will compare
