I have an Aurender CD/Ripper/music server/Streamer, a very good CD Transport and a Audio Research DAC 9 DAC.
Since I have lots of CD's it made sense for me to rip my Cds to the server's hard drive so I didn't have to pay to hear music streamed that I already owned. A few days (or pay your kids to do it) ripping and you are done. Any new CDs get ripped immediately.
So, in every case, when I listen to music on my Analog system, it is always, and I do mean always better. However, my digital setup is quite nice indeed. So, I listen to music that I ripped to the server and it is quite nice.
When I listen to Quoboz (spelling?) it sounds the same actually. However, when I play the actual CD on my transport, it always sound better (not much but better) that the server/streamer.
So, my order of quality (on my system) is
1. Analog system (really opens up the sound
2. CD transport to DAC
3. Streamer/music server, pretty much tied.
I know, I know, people will say that digital is digital and ripping bit perfect should sound the same no matter what. That is not accurate in my case.
They are all (except for the analog system) going through the same DAC so no variation there. They are all using the same type and length cable, so no variation there.
