    Class D or AB? To repair or replace ...

    Interim update: Pioneer A400 I've cleaned up the A400 and it seems to be working fine (save for a noisy volume control - scratchy pot but generally quiet once in a fixed position). Plugged into the Tannoy Revolution DC4T floorstanders, it sounds (perhaps unsurprisingly) a lot better than I...

    Class D or AB? To repair or replace ...

    Thanks James - that's really helpful. I've found it's temporarily fixed by unplugging it for over an hour. It then works again, albeit briefly, but the problem recurs. I'll try the reset. Failing that, since the speaker cables seem fine, etc, I'm guessing it's a power protection issue/failed...

    Stands, slabs and sorbothane - coupling and decoupling on carpeted wooden floors

    Stands, slabs and sorbothane - coupling and decoupling on carpeted wooden floors

    Hi, I have some PMC TB2+ and 1m high Atacama sand filled stands, together with a PMC XB1 sub (a large beast at 27cm deep, 78cm long and about 28kg). I also have 2 sets of Auralex MoPads. I’m wondering what the best arrangement is for setting these up in terms of coupling/decouping in a loft...
