Now, they're linked to Opera's preamp output. I tried playing a pair of CDs/SACDs to do a comparison between SA-17S1-->Speakers vs SA-17S1-->Opera-->Speakers. The difference is VERY noticeable.
I am a bit confused as to the flowpath here.
Your cd player with speakers is using the cd player as the dac,preamp, (and maybe a small amp in there for headphones?)
When using the Opera you went cd player digital out into the Operas digital in? using the opera dac? and the opera preamp, but does the preamp out use the opera amp part or is it just the preamp out to be used into another amp?
I am kind of surprised that the cd player did not sound better. Maybe the cd player and the opera preamp output are both very low level line outs and both need to be amplified. Maybe the Opera preamp output is slightly higher line out then the players.
Any further explaination would be awsome.
