My amp is beefy and the back end is something that really should be feeding a speaker setup lolThey will not be similar. You do need a good strong amp though. While they are described as bassy, I found they really needed bass boost or EQ.
I Really liked them with my iFi Pro iCAN.
I'm definitely getting 400mw @ 600 ohms, Class A, and the 880 just purrrrrs like a big muscle car. To be honest, that's part of what's pulling me to the t60... seeing how it sounds with all the voltage and current it can take there on tap.
Anyway, you've convinced me. And it'll be cheaper, and probably better performing than the alternatives I was looking at.
