aj, thanks for the video. I think with any speaker there is a "best" location. For some reason many manufacturers don’t take advantage of that. Unless the design dictates something different, many speakers will sound best when well away from the walls. Give PSA credit for doing that.
One of the very best sounding demos I’ve heard was at a SoCal dealer decades ago. They set up the current version of Vandersteen 2 speakers (@ something like $12-14 hundred) along with top end Audio Research electronics. The speakers were maybe 5-6 feet out from the front wall and more than that from either side wall. Clean, well defined, extended, and with a huge soundstage. It was hard to imagine a speaker at that price could sound so realistic.
