If you mean the Lepai amps ( from Parts Express ) , I use them for amp-ing the reverb from my Lexicon unit
I also use The Dayton ( 60 watt units ) for some organs with rear or surround channels. These amps are more substantial and have a very smooth volume control. I have 4 units ganged together ( with BIG tie wraps) on a wooden board to make a decent 8 channel amp ( no balance control though ).
I have a small living room where the organ is placed.
Parts Express give money back exchange up to 45 days.
Hope this helps
