Well it has some really interesting and valuable features, one client uses it’s EQ facility extensively , I have experimented with tone/loudness and the low level listening feature, it is a solidly designed and engineered unit.

Review and Measurements of RME ADI-2 Pro (comparison to ADI-2 DAC)
- Thread starter amirm
- Start date
To what purpose? To compensate for the room factor? That would require some serious measurement with the professional equipment beforehand..
A usb microphone and REW software which is free.

I thought so. I do believe that UMIK-1 mike that goes with it can do a descent job as long as you know to measure with it.
Hi! Some measurements from the ADI-2 DAC and Pro taken with the Pro's AD:
(Taken from my German review)
Residual Noise, 524288 FFT Points
DAC Phones (blue): -108,56 dBu
DAC IEM (green): -113,83 dBu - limit of the Pro's ADC. Real value should be around -118 dBu
Pro (red): -108,27 dBu
THD 1 kHz 0 dBu -1 dBFS 30 Ohm, 131072 FFT Points
DAC Phones: -115,1 dB (0,00018%)
Pro (not shown): -112,7 dB (0,00023%)
THD vs Frequency 0 dBu -1 dBFS 30 Ohm
DAC Phones (blue)
Pro (red)
THD+N vs Level 30 Ohm
DAC Phones Low Power (blue)
DAC IEM (green)
The IEM Out starts clipping at about 550mV. That equals the volume setting "-10" at the Phones Out at 0 dBFS. Until clipping starts the IEM has the advantage. So if you choose a setting lower than -10 dB at the Phones Out the IEM Out should be used instead.

I have.
It's as good an implementation as I've heard, but I think I'm just not a huge fan of what crossfeed does.

Welcome to the forum and thanks for posting that.

Sure it is. Not that it will sound any better than $80 Topping D10 though, but it would certainly make one much more satisfied to have it, myself included. It's simply in the human nature..
As a preamp, probably no major difference. But as a headphone amp....I would expect some audible differences due to amp power with harder to drive phones.

I returned my ADI-2 Pro and ordered a ADI-2 Pro FS - just received it. The box & manual etc all still says "ADI-2 Pro" but the front panel of the unit itself includes "FS".
pro tip: I got it a lot cheap than US MSRP - and I didn't pay any import duty from Deutschland....

Thanks. On my side I think I like it but the result is variable depending on the headset.

I have tried crossfeed in the past but didn't care for it. But in the RME the crossfeed helps with the he-400i. I set mine at 2.
Try Lynx Hilo: https://www.lynxstudio.com/products/hilo/This leaves me personally in a quandary of not having a reference class DAC when I return the ADI-2 DAC to its owner tomorrow.

I have to sell a bunch of stuff to afford it now at $2,300 list price.
Looks nice though.Last time I bought a Lynx product was 20 years ago. It was a PCI DAC/ADC.

that test is fraught with problems according to the RME guys, their concern sounds legit but this is not my area of expertise, perhaps Amir could comment: https://www.forum.rme-audio.de/viewtopic.php?id=26885

I didn't know anyone was using diffmaker for scoring of products. I fully agree with RME folks that this is wrong. There are infinite ways for the tool to go crazy even with simplest differentials. I have wasted hours with it and even in the cases of simple control signals, it either crashes on me or produces incorrect results.
My 400i headset broke last week, unfortunately. I had to return it before testing with the RME. It's a shame because my wife was enjoying it a lot.
The effect of the crossfeed is variable depending on the headset (I'm using the Sennheiser HD650, Oppo PM-3, Audio-Thechnica M50x and M70x) and the type of music played. Sometimes I like it, and sometimes I feel like it removes more than it adds. So I can't really let it turned on, but it's still a nice feature to play with. I'm far from being done with testing it anyway.

Review is almost 5 years old ...
I assume they've updated the product but measurements/comparisons might not be as relevant.
