Spendor & SETs

Anyone had experience or good luck with SETs and stand mounted Spendors? If so, what speaker models? I have an Air Tight ATM300 which is nice and strong for a 300B design, what with those Tamura trannies and all. By the way, my room is 11 x 13.5 x 8ft high with plaster walls and ceiling, and I don't listen at head banging or "concert hall" levels.
I drive my Spendor SP9/1 with SET monoblocks from KR audio (vt850). They work very fine together.
There is a great french forum with a new english spoken section where many Spendor and Tube lovers share their experience : http://www.ls3-5a-forum.com
You can perhaps find more specific answers there ...
