I would love to hear other's comments on any of the new Zu' and partnering amps. I was going with Quad amps but have decided on Manley 300B SE/PP monoblocks instead.
Soul Superflys with about 150 hrs on them, hooked to the 16 ohm taps of an Audio Space Ref 3.1 300B. Mission cables all around. I think there's real synergy there.
The speakers are about 2.5' from the back and side walls, 7' apart, and slightly toed-in toward the listening chair.
I don't really have the technical chops to give you a detailed review. I can say that I've been floored by a number of recordings from various genres; heard things I've never heard before, and yet find it easier than ever to get lost in the music. They make the music big.
