I have B&W 803 D speakers, purchased 15 years ago. The dealer had two men deliver them to my upstairs listening room. At the time I was in my mid 40s and in great physical shape. I want to replace the speakers but since the I have had heart and back surgery and no way am I shlepping these downstairs for a dealer to demo in trade in. I bought a 90 pound amp a few years ago and that will reside in my system as well until I move
