Interesting debate here. Again, I’ve said this before, I do believe in science and measurments, but I also do believe that people can prefer the sound of a piece of equipment than an other. I also believe that there is more to an audio product than it’s SINAD at 1K 4V, and also we have more to look at here but it’s still a snapshot, I don’t think it tells us everything about a product. the way they are “ranked” based on this, we sometimes feel that the debate turns strictly to: blue, great green ok, yellow mediocre and red broken.
Now, Ibelieve that this“prove your impressions by a blind test” go-to argument winner is getting old. First, it’s complicated, the easy ones, comparing a bunch of file and go: see, you can’t hear a 1% thd, therefore... see, you can’t here 50 ps jitter therefore... well you get the drill, but never anyone have been able to show me some blind test results between products reproducing actual music trough actual speakers.
That brings me to the subject of the debate. My CD player includes a dual burr brown R2R dac chip (PCM1704), obviously limited to cd format, but my CDs
to my ears sound more “correct” trough the onboard dac of my player than fed by spdif trough my Topping E30. Really I don’t really care if you think it’s my imagination, they don’t sound the same and I have no doubt I would pass a blind test. They are different sounding, and yes I could objectively be called a “trained listener”.
Basically no one can ever show me examples of blind tests that says for example “ If the sinad pass 16 bit of transparency, they sound the same” only “ I can prove you that you can’t hear x% distortion” It’s different.
I’ll show you a blind test result, show me one that says otherwise. OK not about DAc, but one that showed that 6 out of 8 panelist choosed the same preffered vintage receiver out of 3 including a modern one, it says what it says, people can find certain characteristic of audio reproduction to be better than other, regardles of the SINAD
