This is well-made amplifier with the major advantage of being fan-free and hence zero noise. I marked it down on features, because it doesn't have any - it is a dual channel amplifier and that's what it does. (You can parallel the amps to make a higher power single channel amp). If you want a dual channel amp, you won't need features. It does what it says on the tin extremely well. Be careful when picking it up, though - the cooling fins are sharp.
