Terry, I have owned Sequels for almost 8 years now. I currently run a Aragon 4004 MK II, bi-wired. I have had a Parasound 2200, OTL 150, PS Audio 200C and Adcom 555. I have borrowed a McCormack DNA1-Deluxe and think it sounds by far the best of anything I've heard. I'm looking for one to replace my Aragon. I like the 4004, but the Mac's much tighter, sweeter and faster. When you are able to switch them around and hear them, you can't miss it. Having listened to the Sequels for hours a day, I'd have to say the more juice you feed them, the better they respond. I'm talking current, not watts. They drag amps without juice into submission. I love the Aragon on them, but must admit the Mac's the thing for these babies. They sing with it in there. I've heard many others with them, but for the money, McCormack is a great deal. Mark Root
