I am an AER fan, ............ Big Time !I have owned 2 of the smaller Compact 60's ( or Bingo's), the top Acousticube, (similarly priced to the Domino new at over £2000) and I currently have 2 of these Domino amps, which I find to be the ones I prefer.This one is for sale because it has lived in Spain and we now have our house for sale so I have no need for 2 in the UK.It has been used only when I have been on holiday over there and it has been gigged no more than a couple of dozen times, although I am not sure of its age as I acquired it second hand.To my ears, it has even more depth when used with guitar, than the more expensive Acousticube, and is only a little heavier and not much biggger.It is effectively a pair of Compact 60's  with bigger speakers and 4 mixable inputs.
I also prefer the control layout, whereby you can plug in another instrument or backing tracks with entirely independant, not overly complicated tonal adjustment, and still 2 inputs to share, and there are 4 built in effects, assignable to the individual channels.!
