Oh I forgot to say. My speakers are B&W Matrix 804's with with Mundorf Supreme caps for reference
Hi Systembuilder, I currently own the Premier 11a and a Premier 5 which, as I understand it, is pretty much a mono-block Premier 4 (200 W/ch instead of 100 W/ch). The Matrix 804s can demand a lot of current but the Premier 4 should be adequate. I believe that conrad johnson still offers upgrades for the Premier 4. That should tell you a lot about their value.
