Just off the phone with Mr. Vandersteen...
His recommendation-buy Quattro CT's. (He noted that my current room size was on the small size, and the Quattro's would offer better optimization).
Since I just bought the 3a sigs, I don't think it is going to happen.
Regarding the subwoofers, he recommended the 2wq's over the 2w's, as the latter were long in the tooth. And, if I went with the 2wq's that I buy a pair, not a single, and preferably a pair of similar vintage.
But, ultimately he said the Quattro CT's would be the best way to go.
RE: Audioconnection-
I did read through the owners manual, as well as the FAQ and just needed information that I did not find.
Actually, this telephone conversation was rather nice. Though I can't believe he can actually take the time and respond to all those questions.
If you are reading this Mr. Vandersteen, a well deserved 'Thank You'
