Just plugged my CJ350 in, after listening to my reference CDs thru my VAC 300.1a amp. Wow, I guess that's what bass and punch is supposed to sound like thru my Magnepan 3.7s! I kid you not, I muted and unmuted my Velodyne DD15+ and could no longer hear the subwoofer...my Magnepans are now taking over the low end via the Premier 350. I was bracing myself for loss of delicacy at the top, but right of the box, first 1/2 hour turned on the CJ is much better in the mids and highs than I was expecting -- not overly bright nor rolled off. Nice to know the spatial soundstaging inherent in my VAC preamp carries over to the SS amp. Other thing I am noticing is incredible combination of macro and micro dynamics.
