Guys if you think this piece is a joke you are greatly mistaken. One has to spend serious dollars to beat this little thing Actually two is better than one. Run them dual mono and do not look back. If one uses srtictly digital playback has a DAC or Cd player with a 2V minimum output along with an amp with low input sensitivity [ less than 1V or close and not more than 1.5V ].
You my friend are in like Flynn. IMHO this is a freak of nature. On paper it should be just OK. No I am NOT a dealer and as a dealer F'n nuts telling you about it. But that,s me. No its not a Lamm or Audio Hungary preamp as it does not fit all but if the criteria is there to use it it will be the best $112 you spent on Audio. TT does not apply.
