The amp is still with Nick - he is a smart dude. Rev is using a different one, it turns out. The full tube design of this amp makes a difference IMO when compared to the Carver C-19. That plus the dual mono design and the huge outboard power supply (umbilically attached to the main unit - no plug - and almost as big) make it sound kickass. It has these strange gain controls for left and right that at least in Rev's unit did nothing to the sound or balance - I suspect they may have been bypassed in the past by a smart owner. The phono section was not sounding impressive when I was there, but Rev later messed with the dip switches or jumpers to match impedance and that came alive too.
I like this pre, but I am now addicted to the HT bypass feature in the Parasound (and the remote - I know Rev controls the colume of his Apple TV via the iPhone and the CD-80 from its remote, but I cannot do that with my tape deeks). So my next pre upgrade will be a Parasound Halo P7 or the Carver Black Velvet when that comes out (the latter would earn a spot on my rack with or without remote control or HT bypass - assuming it sounds good enough - so I can make the Black Beautys happy).
