    Hello. What is the different about this two amps ? I mean in sound.
  2. None, I think. The mark II is just a version where all the bugs, that were in the old one, are fixed.

    I had the same question. so, what bugs were fixed and does anyone else know of what the differences might be? I am seeing used 1001rb's (not 1001rb-II) for sale lately.

    I have a version one 1001rb. I bought it used and it had been run hard. It showed signs of over heating and both of it's speakers showed signs of distress. I replaced the speakers and have used it ever since. I understand that the first gen ones could be send back and have the updates applied by GK. No idea of the cost tho. I thing the cooling is updated, power is upped too, and you get a different color led.

    I think.
    Maybe Agedhorse will chime in here if he knows.
