    Hi Alan
    That was the other option i mentioned
    Easier than the Khozmo remote and on par in terms of quality.
    Should I ever build another dcb1 that's what I'll use.

    A control board to match can be had very cheaply from China.
    Alan, do you have a link? I've seen the HiFiCollective control board but it's expensive for what it is.

    Ditch the cheap volume control and just wire the motor leads to the motor on the Acoustic Dimension unit.

    Surely putting it in an elegant case is vanity, if it needs air circulation to cool it. It's there to sound good; don't affect that aspect. Perhaps you could aerate (grille?)the underside of that case and have a couple of holes in the upper for exit?
    i liked both my Pass pre and the Stereo Coffee (with remote!) but my Hafler DH101 sounds as good.

    Oh absolutely. But if it looks good, it must sound good surely

    Alan, I presume that controller will also work with the TKD motorised pots?

    I would guess so if the motor is the same at 5V.
