I have a MC275VI, and I cannot imagine letting it go, except if I needed to power monster floor standers in a large room. It's sui generis--you're not going to find anything more organic.

One other consideration, especially with Memento's--are you going to add a sub? This would argue even more strongly in favor of a 275, as a large portion of the brute force power will be delegated to the sub's built-in amp.
