I recently purchased a Marantz SR8001 to power a new system. I mainly purchased it for it's reputation and the fact that it had 4 HDMI which I needed desperately.
I have the 633-T's on order, which are coming in on 5/18 so a little longer... I have the 634VAC and haven't turned it on yet but the quality is there and I'm sure I'll be happy. The 632-IW's look decent.
Now, to the sub. I had the S-12 come in and it looked nice, but I didn't like the fact that I could see inside the port on the back of the sub where there was dust or particles and I especially didn't like the fact that I could see the thin foam insulation inside. It looked like the kind of insulation that I get to put underneath hardwood flooring when I'm working on our rental properties.
In any case, it's going back today. I was fortunate enough this past weekend to demo and purchase a JLAudio Fathom F112, I think that should take care of things.
Oh, and for those of you who are wondering how to mount a 634VAC to the top of a DLP or 'slim-line- TV, well I just went and purcahsed 2 OmniMount Center Channel Speaker Shelf, found on amazon ... (CCH1B) and mounted them side by side on top of my Samsung 50' DLP and all was well. The stands hold a total of 30 pounds each and the 634VAC is 40 pounds... Hence 2. Worked like a charm.
