I've heard both at a stereo shop in town through a pair of Klipsch RF-7 IIs and couldn't tell you the difference. If it matters to you, the Mac amps look amazing. Was a Nad M3 and a McIntosh MA6300. Both were very much out of my range, but the guy was happy to let me sample them. Also included was a Marantz PM15S2.
