Many years ago I tried the Adcom 545 with 2C's, (and several other amps, as it was for a review for a magazine) and had inadequate bass performance. We had much better bottom end (depth and impact) from amps such as the Sumo 9+ and Polaris, the Counterpoint SA-220, the Naim 250, and several others. The Adcom is a decent amp, but not really a great match for the Vandersteens. Find a dealer who will let you audition amps at home.
Vandersteen 2Ce and bass performance
I recently bought a 7-month old pair of Vandersteen 2Ce speakers and stands. I am running them with an Adcom 545 MKII and GFP555 Pre Amp. They are biwired with Monster M1.4s bi-wire. The room is large and hard (windows, maple floors, drywall, and brick). I'm hard up for more bass. I'm particularly concerened with the fact that so much of the musical stage is convincing and yet the kick drum in so much of my music sounds reticent. The speakers are reputed for "excellent bass extension," and I do not remember this reticence when auditioning other 2Ces in a local dealer. Suggestions for how to evaluate or improve this situation?? Any help is appreciated.
