If I'm not mistaken I think Wilson uses Audio Research when designing, and tuning their speakers. So that might represent a good choice. Based on some of the above responses and my own experiences it seems like they both work well depending on your tastes. There are a relatively small number of speaker companies that excel at both but Wilson is one of them. I've heard WP8's driven by Boulder and Mark Levinson and both were excellent.
Hi Wilson W/P8 owners, best amp ever to drive WP8?
I have a pair of W/P8 for over a year, used with Krell 700cx amp. The system sounds great but I crave for a little more warmth and glow in the midrange, overall airiness in the treble and soundstage plus a more natural/real presence of acoustics. I have audition Audio Research Ref210s with W/P8, love the sound but was bothered by the overly full mid bass(typical of tube amp?) and the slight loss of focus and precision when compared to my Krell amp. Well controlled bass and a tight mid bass are top priority. What amps, SS or tubes, have you owned that optimise the sound performance of your W/P8s. Thanks for sharing your experience.
