Pre Amp for Adcom

What do you guy's think would be the best pre amp. to go with the Adcom GFA 5802 300 watt power amp. and Salk HT3 veracity speakers. I have a Adcom GFP 750 pre amp. but just wonder if I could find a better sounding pre amp. any opinions would be appreciated especially if you have tried the GFA with other pre amps.
