my room is 12x15x8 sometimes the bass can overpower a little but the sound is to die for. right now i looking into upgrading the preamp and maybe adding a dac.
I'm curious why your wanting to upgrade your pre-amp. I've heard nothing but good about the 21A. I am using my Arcam AVP-700, but have considering getting a used stand alone pre or maybe the Belles Soloist-3, which many say rivals the 21A.
