My current listening scheme is iphone 4 apple lossless files> Airplay wifi > AppleTV (latest) > optical > Bryston SP2/DAC > Bryston 6bSST > Magnepan 1.7. It sounds nice, and gosh its convenient.
I have compared this to Oppo BDP 83> optical >SP2/DAC, and Oppo BDP 83> analog > SP2 analog
To me, they all sound different, with definite difference in volume, and seeming difference in EQ, but I'm trying to decide if there is a definite improvement in overall SQ. From what I have learned here it seems any decent DAC and decent bit rate will sound the same.
1) Does iphone to wifi to apple TV optical out result in any signal degradation enough to make make a difference?
2) Is there any benefit to going to the wired digital player method such as Logitech Squeezebox, or even pricier Bryston BDP
