Which DAC measurements do you like to see next?

https://fluxlab-acoustics.com/fluxlab-catalog/atlas/
An AIO device (DAC, streamer, pre) from a somewhat unusual place: Ukraine. IANAEE, but that is one gorgeous PCB and the description sounds like some serious engineering expertise was involved.
The manufacturer specs are pretty solid too and the by-ear reviews are also good: https://www.headfonia.com/flux-lab-acoustics-atlas-review/

P.S.
I have no connection with the manufacturer and no idea how to best contact them or whether they'll be interested in an ASR review

With ES9038 Pro. They claim "127db of Dynamic Range" and "THD+N at... -122db".

That reads like chip specs, not the gear. Feature list says no-feedback output stage. As such, I doubt they will remotely hit those numbers.

This seems like a nice balanced solution for the raspberry (?). It even has the fancy Khadas RCA plugs :D

It sure is cheap but with no measurements, it will likely have poor performance. It also has no header to mate with the Pi.

Wow, there are tons of stuff in there:

Drop them a note and see if they send one in for review.
 
Senheisser GSX 1000 (or GSX1200) please.

I am having a tough time deciding if upgrading matters. I read that it's rated 103db. If that's true, that's probably good enough by me. On a side note GSX usually has more views than the Creative G6.

The GSX1000 vs G6 articles/videos completely dominate the individual reviews. Since the G6 has been reviewed, this seems like a 2 for one kind of deal.

They state a THD of <0.001%, aka 100dB, which puts it up there with the $9 Apple dongle DAC, so that doesn’t inspire much confidence in a ~$5000 product. They also say IMD at <0.006%, aka ~85dB, which is even with the Schiit Modi 3.

The Senn has an output of 1V RMS. Who would be interested in an earphone only amp?

It is a cute looking amp that I like to test someday. Alas, I have too much in my queue to test so don't want to purchase it now. Remind me in a couple of months and I might purchase it then.

The es100 you already have, that's my vote!

It is a difficult unit to test because under windows it only works in 16 bit mode which limits its "high-res" feature.
 
Pioneer XDP-02U Retail px is around US-$ 200. My main purpose was to eliminate the RPI or any mobile phones from the chain when feeding my favorite DAP/DAC.

It receives from Tidal or Deezer, from TuneIn and from 2x 400GB mSD (no DLNA/UPnP, no OTG in, only USB-OTG out).

Itself it's also a (Twin-)DAC with a very weak amp section (only for iem's).

More info: https://www.pioneer-audiovisual.eu/eu/products/xdp-02u

Would love to see checked it's OTG output in comparison to a mobile phone.

Where do you recommend I read up on to understand more about 16bit vs 24bit and how it effects dynamic range, dac performance, etc.?

I've seen some comments here that make me wonder if a decent dac is even necessary(beyond a khadas tone board or something) if you don't have 24bit files.
My current audio player that syncs to iTunes is only bit perfect on 16bit files for example.

You don't need to worry about that in this context. I am commenting on it advertising high-resolution support but is something that I can't easily test on Windows. Oddly on MacOs it supports 24 bit.
 
I'll add another vote for the NAD C 658.
I'm really interested in this. To me this seems from a component selection to be exactly what I would like for a one-box solution, since it also includes Dirac Live. However, considering the measurements of the other NAD offerings on here (disappointing at best) I'm far more cautiously optimistic... if I can even still use the word "optimistic" at all. I'm at least hopeful that they were able to do a better job at a Sabre implementation than their custom DACs.
 
Still hoping to see the new Matrix Audio X-Sabre Pro (MQA) measured at some point...
