    Default [FS] Parasound Halo A21 power amp.

    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.
