Beyerdynamic A1 vs. graham solo...
I was about to plug the trigger on a graham slee amp, when I realized that the beyerdynamic A1 amp is about the same price in the US as it would cost me to get a graham slee amp.
Beyerdynamic A1: $850
Graham slee solo with PSU: $750.
I can't really audition any of these. What's a better value?
