I vividly remember testing Rush's 2112 on the original perspectives and the Perspective 2. The way those speakers untangled the layers of guitar so effortlessly, including that shimmering/ringing tone of Lifeson's guitar (also on Hemispheres album) was wonderful. They didn't have quite the thickness of the guitar parts as on the Devore O/96 speakers or my Thiels, but it was so tonally beautiful. I would not own the Perspectives if they couldn't rock, though.
I've been blown away playing tracks like Rush's Hemispheres or Tom Sawyer on the Perspectives in my home. Amazing punch and dynamics especially in the bass and drums. From what I've read, the Perspective 2 are even better in that regard, so I'm looking forward to getting my upgraded pair back for a listen!
