Hi I have in the last few months upgraded my reciever from a Yamaha V596 to a Pioneer Elite VSX82TXS and the difference in sound is amazing. I have B&W 603 S3 mains and was always a bit unsure if I really liked them or was just convincing myself that I did. Now I know I like them. Anyhow they are currently bi-wired and since my new Pioneer has the ability to bi-amp and I will not be going 7.1 I am tempted to bi-amp the B&Ws. Having never bi-amping anything before I am just wondering if it is worth it and will it make much of a difference in sound.Are there any draw backs in bi-amping? Or has any one had any experience bi-amping using any of these components.

Thanks for reading Jim
