I've heard the 7b and I believe the 2.4 and personally I would go with the Aerials. I found the Thiel's I listened to to be a bit too bright for my taste.
Aerial 7B vs. Thiel 2.4
I am building a HT system and am wondering what other Audiogoner's think about building a HT system around the Aerial products (7b. CC3b and LR3's) or a Thiel system (2.4 as mains, MCS, and 1.6s). I think the Thiels are extremely revealing whereas the Aerials tend to be a bit more mellow. I will most likely be using Krell Showcase as the pre/power combination. Thanks.
