Upsamplers, DACs, jitter, shakes and analogue withdrawals, this is it.

Thank you. Will you please clarify these comments....

Thanks for your reply Ferenc. I hope you are not annoyed with the several follow up questions. I can understand if you might prefer to address them in another conversation with Rushton for possible publication.

[Abe]: For clarity I wish to keep the network streamer and DAC as separate items even though we know of products that incorporate both in a single chassis.

[Ferenc]: "But dozens of other reasons LOCALLY, mostly in the analog domain of different audio subsystems in the streamers, dacs, etc. The last few meters is the most important of the long data chain."

[Abe]: When you say "mostly in the analog domain" are you talking specifically about truly analog subsystems like the analog output section of a DAC and the analog components downstream like the preamp and amp? Anything else?

[Abe]: What do you include in these "last few meters" of the long data chain you mention above?

[Ferenc]: "From a strictly information technology POV there is a good chance that the 100 USD and 30k USD streamer would "sound" theoretically the same, but their noise signature, generated noises, noise isolation can be very different, and they will not sound the same of course IN an audio SYSTEM."

[Abe]: I can agree with the "noise" part of your comment but in the grand scheme of things does this "noise" below a certain level in the streamer even matter given the input reclocking and signal conditioning taking place in the digital domain within modern DACs before analog output?

[Ferenc]: "Most of the digital (data) communication happens in the analog domain."

[Abe]: You lost me here. Please elaborate. And we're still talking LOCALLY right?

[Ferenc]: "So the analog parts of any digital system are crucial and effected by analog problems."

[Abe]: Can you be more specific? Your reply is ambiguous to me. What analog parts of the digital system?



Thanks!
