Pete, I too have a pair of grade A 751's that are tucked away. I'm using a pair of B&W CDM4 floorstanders in my system which are very good, well over six years old, if you like the 751 sound you will find B&W a close match (not my particular model). The 751 was the best speaker Mission made, you can still get replacement bass drivers but not the tweeter, worth investing in if you intend to keep them. If I were you I'd hold on to the 751's and consider updating your stands and cables, they improve the more you spend on them...
