I'll take my 32 wpc Pure class A ML3 Signature with my X2's over the big powered amps. I've used both and prefer SET on my Wilson speakers
Steve, that makes perfects sense. However, you are fortunate that your speakers work well with low output amps...plus they do not have a nasty impedance drop for the amp to deal with.
One of my a'phile friends just sold his lower powered amp because his new speakers have a vicious load characteristic that requires a brute of an amp...even though this speaker is using small drivers ( 7-8") in the bass dept.
Most Wilsons that I know of, require a very hefty amp upstream, one that can push an unfriendly load. Also, since most of these models are deigned for a larger room, the partnering amp had better have some serious muscle.
BMCG, I do believe that what i posted above is a major factor. Sure there are some very expensive SET's on the market, but to the --shall we say- "less experienced" hobbyist, they will have less appeal at the dealer than the mega powered amp with the mega price tag. That dealer can now state that the mega powered amp is a perfect match for the Wilson under consideration.
