Wlutke, if you can find a pair of used Quatro's I think you'd be in heaven for your Rock. Even the other ones move a ton of air. I personally only like the look of the wood versions, but I've heard the sock Quatro's set up with highest of end CJ with all the tweeks and top cabling and was blown away. I've also heard them with NAD separates and an Ayre Codex DAC with basic Audioquest cable and it sounded incredible.
To me, that's hard for most speakers to pull off. You made a salient point to me on your moving air issue. I'm totally on board after rereading your posts etc... I never thought we were that far off and I think I'm much closer to what you have posted about the movement of air deep down. Some, like you, really need that in order to get 'moved' (pun intended). I'm not quite like that as I need my music to give me everything else. Hey, the Treo's go very low and move a bit of air when set up properly. They are very satisfying to many and that's why the Quatro is out or those top subs he sells. I want the Quatro for myself due to the tunable bass, but deep down (no pun), I want more air movement on the bass, but I hate most subs as I need tuneful bass that is articulate and homogenous with the main speakers. I hear coherency in speakers more so than many do and that's what drives me nuts about so many manufacture's who make and market high end speakers. So many are not coherent. Richard nails it and always has. My Proacs were the same way years ago. The newest Paradigm Ref speakers I got to hear last month on pre release were also pretty amazing, but they cost 7 or 8k more than the 5CT's and are not nearly as good.
Folks can set their price range and figure out what's most important to them and see if they can fit it in. I still feel that out of all the Vandersteen speakers ever made, that the Quatro is THE sweet spot in the line for price/performance. JMHO
