You will never know or hear the potential of your B&W's with either. Back in the day (early 90's) so many sold their 801's and were driven by entry level high end components. The B&W's will sound good with most gear but will excel and reach their full potential with McIntosh or may I say Krell. I have been using my Krell/B&W match and have not worried about upgrading. If you stretch a little to make it a great match it will pay off two or three times by not getting into the upgrading "buy and try" cycle. Been there, done that, take my word. Get Krell, Levinson or McIntosh whichever is your cup of tea ten enjoy the music.
