Hi, I am wondering which would give a better performance for my HD600. The O2 amp or a fiio e9+e7.
What source(s) are the amp or DAC/amp going to be plugged into?
O2 + Schiit Modi. No kidding.
Looks ugly but sounds great!
Uhm... if you're just gonna get the O2 amp then you're pretty much going to be using the DAC from your Macbook. The E7 + E9 combo would easily be much better then, since the E7 > Macbook.
Amp wise alone, the O2 is cleaner and has a lower output impedance.
