The 5's would have been fine in my room. I have plenty of friends who have small spaces and love their 5CT's. Personally, I feel the Quatro's are the sweet spot in the Vandersteen line and I'm not made of money. Iol.
I rarely second guess my audio purchases as I'm so anal, that I put a ton of time and auditioning in before any purchase. I know the Quatro's will sound outstanding with a built in crossover in my Ayre AX5/20. I've heard the 5ct with the AX5/20 on a few occasions and it sounds great, but personally, I like it better on the Quatro's. Again, I used my ears and not specs to figure that out, lol. Bob, I really think you will love the Treo's with the amps you have. :) pete
