The Belles Aria Stereo Amplifier is a 75 W x 2 solid state power amplifier.
I can't seem to find any other info on the web, other than what's on the Belles website at https://powermodules.com/aria-stereo-amp
That said, this amp sounds wonderful.
Very smooth and velvety, yet powerful, and almost tube-like.
Power cord included, as well as original box, and owners manual.
