meanwhile, I have a GFP-565 for sale for $299

Yeah, I've had a GFP-345 for a while, basically a GFP-555ii minus tone controls and phono - Lab out is cool if you've got a wide bandwidth power amp. Sounds like not much at all, really. Maybe very slightly on the warm side but I'm really stretching. Nice soundstage presentation.
Sweet.
