I understand Mcbuddah's comment, but don't agree that it takes mono blocks to get the job done. The 500WPC is a dual mono config I believe. So the essence of that is already there.
My only concern was the 'voicing' of the amp/preamp--and from what I read, it's very detailed without being too etched. Of course reviews can be fools gold, we tend to read the comments selectively, seeking out that which agrees with our needs.
Thanks to Mapman too. Bel Canto deserves a look too, I suppose.
