What makes One Music Server Sound Better than Another?
The point of this thread is to ask, how come I perceive the the DejaVu server as sounding better than the Antipdes DX?
what are the technical reasons one should sound better than the other?
Some people are comfortable with using pattern-over-process in their purchase-making choices. I suspect you will not get a response that details process. Always patterns, which require less diligence to describe than process - it’s easy and feels as real as could be. Seems pervasive, but perhaps less hazardous in hifi discussions than in politics, education, etc.?
So to answer your thread headline question:
Opinion.
(+bias?)
Your two boldface questions, @mitch2 : the first one is answered by psychology textbooks nearly a century old and/or ethology / consumer preference studies in peer-reviewed lit up to this day. Your second question will probably not be answered because, thus far, no evidential support for such a thing seems to exist.
Plenty of reasons given for servers to “sound different,” but if they’re all opinion, a good third boldface question might be Why doesn’t this standard change? Rhetorical question, that is. 😉
