Best preamp under 5k for Krell amp


I have acquired a brand new Krell FPB 300c amp and with what little money I have left I need a preamp. I will be powering Martin Logan SL3 speakers. All advice appreciated.

Perhaps this needs a new thread but:

I auditioned a KRC-3 with my system: Thiel 3.6s and KSA-150 amp. I liked the sound of it, soundstage, imaging etc. My brother thought it sounded too bright. When I talked to the dealer about this, he said it was most likely my source that was the problem. The KRC-3 is a neutral sounding preamp and will only transmit what it's receiving, he said. If there's brightness or errors in the source, the KRC-3 won't fix that. Anyone have experience with the KRC-3 and have opinions about it. Still on a quest for the right preamp for my system at the right price. Right now the Adcom GFP-750 is looking like the best bang for the buck.
justin, before committing to the adcom, i'd still give a melos pre a try... the sha-gold/maestro series can be had for about the same price...
