Hi James - sorry missed your post on PFM, will pop over and have a lookt at it.

Don't worry re the pdf - it's one of the first thing I did when scouring the www for info on the amp. As to how I'm getting on with it? I've been very pleasantly surprised at how good it is - it just doesn't add anything, it's just so transparent. I did seem to have a channel balance problem - slight bias to the left so did all the usual checks.

Ended up running the whole system L to R ie every connection from the inputs to speaker outlets is running opposite way round - it ends up correct at the speakers which is the main thing. Result is the sound has centred. Lord knows why - doesn't make sense at all - but the amp's left and right sides are doing the job of their opposite channel. May be psychological...may be an acoustic/phase anomoly in my room.

The amp really is a cracker though - a fair bit faster than the Claymore and in one swoop my bass issues have gone. I knew it was the amp...I should trust my ears a bit more often. The Claymore does seem to like a less lively room, and taking it to a mate's house it worked beautifully. Will still miss it, but more out of a sense of nostalgia from my Flat-Earth 80's days.

The Sony has a cooler, more simple presentation than the Claymore too but once let off the leash it really hits hard and latches onto rhythms as though its very existence depended on it - it's very funky! Seems to like being driven too - doesn't sound as inspiring at lower volumes, a bit flat even. I'm certainly very happy with it, and for what it cost I have no complaints - it may even surprise one or 2 people at Scalford on Sunday. Will hopefully have my PS-6750 turntable up and running as well.
