Like new, in excellent condition with all original packaging and manual.
Solid State Class D amp - has both RCA and Balanced (XLR) inputs.
Not too many reviews out there but the few you can google are positive.
Unit is very efficient - delivers a lot of power without any problem AND without generating any heat whatsoever.
So besides the good sound and great build quality you also get an amp that doesn't care if there is any clearance around it....
