I finally got to put together my new HT this weekend and did some listening. I decided to do some music listening first to get a feel for my mains (PSB Image 5T). I can't say I'm disappointed but I'm not impressed. They seem little thin to me. Imaging is good but the mids and low end definitely are missing a fullness that I expected. I'm coming off a set of bookshelves and these things don't seem to have the punch I thought they would. I am using a Yamaha RXV-640 that pushes 85w per (or at least it says it does). Are these speakers power hungry and I just didn't know it? Will changing the speaker position matter much for this problem? I added in the sub and it sounded better but there is definitely a hole in the bucket somewhere. P.S.- I took back my Velo DLS 3500 and got a Hsu STF-2. I'm still playing with it also. Don't know if it was a good move yet or not. Also found out that CompUSA has a 15% restocking fee if I take it back. Dammit, may have to do some packaging tape artwork if it doesn't work out.
