After so much discussion and several suggestions and distracting sambar talk, hope you have a better sense of what you want?The audition was done in a controlled environment at a dealer’s place. The wiring he used is top notch I can say. As I said before & simillar to what you are mentioning, B&W might need some care in choosing partnew equipment.
1. Continue with the current AV receiver and chain but change the speakers?
2. Select a dedicated two channel amp and speakers for a dedicated music set up
3. Use your current front pair speakers but add a stereo amplifier
Other options?
