For what it is worth, I went from Martin Logan Aerius to Wilson Sophia 2. I had the Aerius for 16 years or so, and I was very familiar with them. As soon as I hooked up the Wilson's I jotted down some notes while the Aerius was still fresh in my mind. I am also running tube amplification, Music Reference Rm-9 MKII amp, about 125 WPC, and a large room 18' by 36' with openings. So far I have not been wanting for power, but then again, I have not tried another amp. My system consists of:
VPI Classic 3 Dynavector XX-2 MKII, Avid Pulsus phono stage, Acurus RL-11 Preamp, Music Reference RM-9 MKII amp (Genalex Gold Lion KT77 and Russian 6922) and Sophia II speakers.
"I like them better already than the Martin logans, so much more articulate. And they crank! Bass is way low, like a sub, but very balanced on all frequencies. Big surprise is they image better than the logans, 3 dimensional instead of 2. Plus the midrange is way better. I only played a couple of albums so far. But Yes, different class of speaker. Much more detail in the mids with great bass extension. I really like the 3 dimensional image. The Martins were not as 3 dimensional in the imaging. No box coloration, I am very happy about that. Box is completely inert."
