  1. It is really crazy to think how the audio signal path is going to be so radically simplified (see John's explanations in my last article). Not everyone is going to be convinced by this approach. If you consider that each analog component (cables + preamp +amplifier) inevitably deteriorates the sound (and the best ones simply offer less deterioration) then the powerDAC concept may be appealing. I'll qualify this view as the "accuracy camp". If you consider instead that each component "enriches" the sound in some way, then the powerDAC is probably not for
  2. It's easy to verify that what you call "network improvements" have nothing to do with the data by doing a bit perfect test.
  3. That's addressed in point 9 of the article, and the answer is unfortunately "algorithms"
  4. The fact that it's easier to put out stuff means there's a lot more "crap" out there, but hopefully also some things of value.
  5. Not sure this is the case. There is an authentication mechanism. Security token is send with a streaming request. The token is checked before the file content is streamed.
  6. You misunderstood or misread me. I am not saying the DAC I mentioned is better overall (better than what?) I am just saying that the designer specifically adressed the issue of source dépendancy. Some of us confirmed it worked (blind or sighted). The term "poorly optimized LAN" is, relative. You don't know what a well optimized LAN is. Is it this switch or that one, with which power supply? With which clock? Some people are cascading these things - is that better? No one knows how far a solution is optimized...
  7. Using a DAC with an electrical connection to the rest of your system is asking for trouble. This is the case with USB, SPDIF, AES, I2S or Ethernet inputs. These connections are in fact like highways (with several Ghz bandwidth) for noise to enter the DAC. Lowering noise in your "source" is not something that can be done with any reliability - you would have to measure exactly the spectrum of noise, and that is not possible as any small change is going to matter and every single configuration is going to be different. The best approach, and probably the least costly, is to improve
  8. One explanation and solution is given here: Not everyone who has tried it agrees with the claims (a few of us do) but the explanations are interesting. Alternative solutions (but not explanations) are given here, for example (though I think even with all this Qobuz is not quite up to the quality of local files either): This is just one example of a network configuration. There are as many as there are users on this forum. No guarantee of success with this approach. Or you can just forget about the whole thing and try to enjo
  9. I was wrong, there is hope - though I'll never fit the Duke Ellington Orchestra in my living room, I may be able to get in the studio with them. Well, not quite, because they would have had to record with modern technology in high-resolution (192 kHz ?)... Here's a session I would have enjoyed: "Jazz Party", at Columbia's 30th Street studios. Dizzy Gillespie dropped in, as well as Jimmy Rushing. The original LP was released with applause added in. Another version is available without, and in amazing sound. To get back to the point... I've been told h
  10. Please stop commenting here !
  11. What are you complaining about ? You tell me I am wasting my time "flogging a dead horse", and I tell you not to waste your time following this. If you think that was unpleasant, let me make it clearer to you: get lost. I don't need your lessons and pity.
  12. We'll see where this takes me, but you don't need to come along for the ride.
  13. I tried to respond with humor to something that was IMO absurd - sorry the second degree escaped you.
