Get rid of that Preamp in a hurry... If you are happy with the sonic performance of your speakers...as far as the musical characteristics... then definately get a good preamp. Try an audio research, or if you dont want to break the bank... a good preamp for the money is a b and k
pro 10 mc....about 300.00... spend the rest on a nice dual mono amp... aragon, 8002 or 8008 bb this will only compliment your system.. provided that you want to stay 2 channel. Another nice amp that i have had is the Musical fidelity a3cr... about 1k used.. the classe ca 150 is nice and even the macintosh mc 122.. all nice pieces.
Good luck
