Sadly having to sell this. I only bought it in October, but I need to simplify my system even more, so my wife can use it. So now it's down to an integrated Accuphase E-207.
This is the second one I have bought, I just wish I could afford to keep it. It will drive practically anything, is silent, and has delicacy as well as power.

I'm asking £1500 for it, with original packing, and I can deliver it within a reasonable* distance of Plymouth, or postage at cost.

About 6 years old now, I believe, according to mickhick1, from whom I bought it. In very good condition, of course.

I am doing a record fair in Bridport on the 13th August so, if Dickie and I can meet up on the day this can be brought back awaiting a future Wam Taxi.
Nay, if a potential buyer were near me in Chichester, or en route, then job's a good'un.
I know its a few weeks away, but nothing's racing out of the classifieds at the mo', particularly..
