I purchased this preamp based on a recommendation from my local audiophile sales person. Boy did he hit the mark. When I connected everything up the way I thought was best and finally turned on some music I actually had to go back and check to make sure that things were connected correctly. The Axiom speakers which I used for 2 channel audio were singing like I have never heard them . I even thought that my subwoofer was still connected.

I have not used a subwoofer in my 2 channel since that day...(except to show friends the sonic difference)

I have owned many processors and preamps, this Moon is exceptional when connected to high current amps, any of the ones I own have opened up the Axiom M 80's to unbelievable sound.
