If this amp has you WOW'ing then why would you want to revert to your old amp? Just listen at a lower volume setting, & you should still feel the players in your room.
Sound is too big for my room.
I just got an original B&K st140 amp and PS Audio 4.5 preamp. I use them with my Music Hall MMF CD25 and JM Lab Chorus 706 speakers. The sound in straightire (passive mode) is great. The B&K has really tamed the highs. Everything sounds like natural, live music. The B&K really brings the bass out in the speakers. WOW! The soundstage has disappeared as it seems like the players are in my room. The problem is it sounds so live their are no boundaries to the sound. Most of the imaging is to the rear of the speakers and along the width of the room and Im in a small 10'x14' room. I think my room is too small for this set up and Im considering going back to my Arcam A65 integrated. Any tips or should I just sell?
