Well, I've only been into this hobby for a short time, so my opinion may not be worth a lot, but I do hear a difference. There seems to be more power behind the music, more clarity, and also larger sound stage. I've been messing with so many variables that just positioning the speakers has also probably helped, But again, I do think the biamping helps.

I'm using one amp for each speaker (vertical biamp) versus horizontal. From what I've read doing it this way with identical amps is recommended.

Anyone have experience with the outriggers offered as an option? Are they worth the $240?

Thanks!
Steve
