Sadly having to sell this. Again! It was for sale in June, but that didn't work out, but now I have an Accuphase E-480.
I bought the A21 in October last year, but I need to simplify my system even more, so my wife can use it. .
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.
Images below copied from Mick's original advert, as my phone camera isn't nearly as good!
