Just got my E30 today.
Will comment after I have some time.

Topping E30 DAC Review

yt has pretty low audio quality.
Try to download some 96kHz @ 24-bit files in FLAC or some DSD files.
How are you getting it to work on Mac? I thought they only had drivers for Windows.
Ya just plug it in!
Btw are you using Wasapi Exclusive or ASIO?
I was testing E30 today, but this is second Topping DAC where my results don't match with results here. D30Pro wasn't that far, D90SE was in the middle, but this is furthest away.
I only tested few things because I got so much demotivated by the results.
DAC set to Filter 1, DSD filter to the lower frequency, DAC mode. Source is Linux.
At this point I got too demotivated to continue and gave up.

Interesting, @JohnYang1997 said this works in 'DSD Direct' mode when in DAC only mode.
Does volume control get disabled? You're sure you're in DAC only mode?

Referring to the 44.1 khz result:
So how do you square this with Amir's results in the review? I think he uses 0 dbFS for the test signal. What results do you get if you drop the test signal to -1 dbFS?
Something is drastically different in your result showing 3rd harmonic of -65 db vs Amir's less than -120 dbFS. What is the output voltage you are getting here vs the 2.145 volts Amir used?

According to manual, input rate is shown on the display in DAC mode, and volume in Pre mode. DAC display was showing only input rate, never volume setting. When the device arrived it was set to Pre mode and changed to to DAC mode.
I tested number of PSU arrangements before I settled for the setup with least noise.
Above plots are with -3 dBFS input data level. TPDF-dithered 32-bit data.
After this, I swapped in D90SE (once again, after many many times) and played same 1k data, measured from unbalanced output of D90SE (E30 has only unbalanced outputs):
Earlier D90SE results with same analyzer are from balanced outputs, except 5, 10 and 100 MHz plots which are from the unbalanced output.
I don't remember anymore what exact figure I got for -3 dBFS input. Just that it was something pretty normal.

no. you are missing the point though. I haven't gotten around importing my flac files on my mac yet. but shouldnt audio quality be identical since the DAC is just translating digital to analog? even from listening to stuff on the browser. but audio quality thru windows > e30 is so far way more clearer and crispier than the mac m1 > e30. I still value general listening on general content consumption equally to serious listening with high quality files.

i just plugged it in. bought a usb c to b cable. it's the same brand cable i have that I use with my windows machine to the e30
They keep updating the E30. Multiple changes have been made to the layout. It's not only that they changed the receiver chip from AKM to CL, but there's more to it. I owned two E30. One serial 2007 und one with serial 2102. Both are AKM receivers. The 2102 was the last batch produced with the AKM receiver chip. I kept the older 2007 serial and gave the newer one away, because it sounded a little less crisp/a slight bit more dull overall. However the older one sometimes produces popping with Roon+HQplayer if I'm not aware. The newer one was quite in those terms. Yet I kept the 2007 because it sounded just a notch more "open".
Serial 2007: More crisp/open- problems with switching frequencys sometimes resulting in popping.
Serial 2101: Less crisp/open - no problems with switching frequencys sometimes resulting in popping.

Ok, opened mine. The right size is 5/64 (1,98mm) aka #2 or #3.
No need to touch the front panel at all, just take the 3 hexes (screws) out, and with a long flat screw driver you can disconnect the flat cable.
Be gentle. Patience is also the key. To assembly back, just use the same process in inverse order. I had no problem in doing so.
Well, first impressions... it had a lot more flux than my D50s on PCB's back. On D50s it was almost clean, on E30 not so much.
Mine's is a 2107. About the sound quality, that might only be true for SPDIF/Toslink, however I don't use it at all, so to me it doesn't makes any difference.
I use Dolby Atmos and let it on Music+Detailed configuration. I'll see how diff from D50s this puppy is now.

Yes. Generally I only measure through USB unless device doesn't have USB.
Mine is with AK4118 S/PDIF receiver. OPA1612A op-amp. AK4493EQ DAC chip.
Device serial number 2102731184

that is expected. Today's computer audio is pretty good.
Most products introduced here only have measurable advantages, not audible ones.

Well, there are some differences on audio here and there compared to D50s.
Btw, my E30 unit has firmware v2.10 on it.
