I think the speakers have the most to do with it. Mind you I don't have a high-end system but when pitting kef r11's non meta against everything in the room at magnolia, one thing I noticed was that the kefs had an unusually deep sound stage..I wasn't listening for it, I just noticed it, and it was the first time I ever heard a deep sound stage and as you probably know all of the speakers are very close to the rear wall in Magnolia I ultimately chose them over theB&W 702s2s I have them set up in-between 2 rooms with about 12 feet behind them, using a Denon 4308, similar to the Marantz that they use in Magnolia, so nothing special.. the recording has a lot to do with it I found that with live jazz I can easily pick out the location of the instruments. Some many feet back,The whole sound is very layered.. and as one other reader had said, shutting your eyes makes a big difference especially at night.
