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.

I have a Sonic Froniers Line 3 mated to a Krell KSA200S. For speakers I am using a pair of Ohm Walsh 300's. I am very happy with the way my system sounds.
I have Sony SACD to Morrison ELAD preamp to Kef Model 3-2's in dedicated 2 channel listening room with Bag End stereo bass support and after trying a dozen or more high end and ultra high end and you gotta be f...... Bill Gates high end preamps, both subjectively and by measurements, can say without peradventure or fear of contradiction, that the ELAD is as accurate as any preamp on the market(what goes in comes out) and is an absolute steal at <800 bucks US.
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...
