I always thought the 7007 to be an excellent unit. Does the turntable have the MMC20EN fitted? if so, you're going to have to go quite a way to find anything for a typical Thorens deck/arm to equal, let alone better it...
May I very respectfully suggest that the KEF Concerto on low stands (NOT on the floor please) would see off most B&O speakers from the late seventies/early eighties in sound quality if not appearance (grin). If you really want to use B&O speakers with the 7007 I'd suggest some 3800's or 5702's, which are far more in the Concerto's ball park in my opinion.
Having said the above, we sold most of our 7007's with S80's, because that was "the" B&O speaker to use, but from the listening and comparisons I did at the time, they really were the weak link on that system when compared to the British alternatives by KEF, B&W and Spendor for example.
