HiI do not own the Sapphires but the M3 Triode Masters which I switched into my system yesterday. I typically use lower powered SET or PP tube amplifiers and am running them with the Luxman Sq 150n...10 watts.
My other speakers are custom Altec 601c and Altec model 14, horn speakers. All I can say is WOW....the Spatial have an amazing sound stage and I did not encounter any issues with mid-range or highs....it is truly a remarkable sound.Placement is key and having enough space for them...they do need 36"-50" from the wall, and are maybe not for near field listening, too son to really say .
I bought them without hearing them....was a good choice for my system.
