As noted by the title i currently have two A20 amps that are doing duty in my Active system . In the new year I may well be altering this set up to a three way and so need an additional stereo power amplifier . Any of the smaller NVA amps A20 , A30 , A40 etc will do and they must be fully working please no projects. Not too fussed if there is cosmetic damage but that needs to be reflected in the price .
