audirvana does make a difference. you get some phase and time alignment voodoo as well as some system optimization benefits. i have mentioned before, i had an all JBL LSR 3XX system with subwoofer and I could not get the pacing nor timing right until I added Audirvana... that was the missing link. And it sounds great.
Difference between Bluesound Node 2i and Cambridge CXN v2
Looking at both of these units and I know there is a $500 difference but can anyone tell me the differences between them and which might be better? It seems as the CXN uses dual DACS and has balanced outs. It might actually sound better but any help would be appreciated.
