For Sale is a very good condition Acurus A125x5 by Mondial.
If you're looking at this, then you probably already know that this is a beast. If you don't know, this is an overbuilt amplifier, made in is the USA, and pumping closer to 200WSound is neutral and punchy.
I would rate it 9/10, but due to the age, it is 8/10.
I do not have the original box, but I have the original box and packaging for a200x3 (both inner and outer box). I'm willing to part with it as I don't think I ever sell my a200x3.
