Hi,
I ended up buying a set of D10s with powered woofers from Ty. The speakers are a revelation as compared to my DQ20s. Of course they are in entirely different classes; however, I'm still very impressed by the D10s. Huge sound stage,accurate,easy to drive, and truly full ranged. In addition, Ty was a pleasure to deal with in every way. I'm very happy with them, and expect that I'll own them for many years.
Regarding the comments above about my other equipment, I am considering adding a stereo preamp for two channel listening. It will likely be something with HT audio pass through so that I can still use the AV7005 for HT. I have a challenging listening environment, and I've been generally happy with the results using Audyssey.
I'd welcome further feedback on my amplifier though. With the powered woofers, the Sherbourn has ample power to drive the D10s. So, are your comments from experience with the Sherbourn, or just general comments about the use of high channel count amps for two channel listening? FWIW, my listening is probably 80% HT and 20% two channel.
Thanks for the feedback.
