Here is your homework (regarding 'baseless'): https://www.audiosciencereview.com/forum/index.php?threads/e1da-cosmos-adc.27038/post-961920

Your quote of my text makes no sense to me and seems fully unrelated.

Why not saying who so we can thank him too? My bet is on @mc.god...

That quote is 5 years old. Today there exist two cheap integrated circuits that are used in perfectly working isolators for less than 50 bucks. You do need an external power supply for the Babyface, but that would be the same with any isolator. For those newer versions search ASR, they have been...

Are you sure your DSD stream is stereo, not surround?

Sounds like wrong adapter shorting outputs...

Isn't it the other way round? If you can't hear differences (that not exist) your ears are golden?

It's a pity @amirm doesn't do fun measurements like that - what is the maximum SPL or milliwatts that cause drastic rise in THD at 20 Hz. I don't have the equipment to do that. With normal headphones one can shove earplugs into the ear canal, then listen at lowered volume to the point where the...

I had them running on the ADI-2/4 TRS output in High Power mode (my ear drums still flittering) with around 400 mW. Do not try that...

Only 22 € over here - ordered. USB meters with USB 3 data through are rare, and this one even guarantees 10 Gb/s - nice. But it will most probably not work easily with USB-A devices (via adapter) and simple USB-C implementations (missing the 5.1 k resistors). Let's see...

Not pricey, but yes, some additional costs. If none of the provided ones could give a good seal then you might need extra large. Two recommendations for 'bigger' ones: - Divinus Velvet Wide Bore in L - AZLA SednaEarfit Origin in L Both have a wide diameter on the umbrella, but are very...

I am curious - did you ever measure what 15% on Windows volume slider really means? For example in AIMP volume slider the 15% give around -16 dB (unless you activate the log option), which matches good enough. But with the volume slider on the right of the taskbar in Windows 11 set to 15% I get...

The answer has been mentioned/explained here several times with nice graphics, but I coudn't find it when searching. 24 kHz for 44.1 kHz sample rate was chosen because it relaxes the filter and phase deviation around 20 kHz, while at the same time anything mirroring back (if at all) will never...

I am not aware of any device reaching such values at an unbalanced TRS output. Plus these values need some perspective - you won't be able to hear any difference from 30 dB up. It is more about proper design and build. For me, reaching stable >70 dB at 32 Ohms and up is nothing to complain about.

Exactly. The ADI-2 Pro had no change in used AD/DA and overall performance, except for the change from AK4490 to AK4493 in earlier times and the introduction of FS clocking.. Here is an overview of all models: https://forum.rme-audio.de/viewtopic.php?id=32506 All ADI-2 Pro versions use AK5574...

Good catch. I did not perform the measurements in the 'intuitive' order, and the AP software does not allow any reordering. So the manually given labels in the right legend were in wrong order - my fault. I uploaded the corrected version.

Bravo-HD, like with Fosi DS2 and others.

'This russian website' confused me a lot by talking about 'clicks', a very clear and defined english word, that seems wrong for the content presented. I hear no 'clicks' in any of the sample files. What there is seems to be what is shown at the bottom in the zoomed waveform. The small dents in...

Yes. And while the output is not galvanically isolated using an 'electronically balanced' output (99% of devices have that) into any amp that has an balanced input typically solves ground loop issues.

So that matches my value (with signal above -143 dBFS) quite well. The AP SNR measurement is a fixed, quick measurement process, changing between active output level (adjustable values, here 50 mV, 1 kHz sine) and silence, where this silence (digital zero) is typically not zero, but a very...
