Replacement for Benchmark DAC Preamp

Hello. I just acquired both a McIntosh CD player and Benchmark DAC with preamp function. I am extremely impressed with both pieces of equipment, though the McIntosh's internal DAC edges out that of the Benchmark. So I am using the Benchmark's preamp function to control volume, with a great old McIntosh MC2105 providing amplification. This combo sounds great.

So here is my question. The Benchmark is a waste if being used just to control volume, obviously, because the DAC is not being used. Can someone recommend a solid state preamp that will provide functionality and sound quality similar to the Benchmark preamp, or better? I am also thinking of selling the Benchmark and the McIntosh amplifier and buying a modern McIntosh integrated unit, which should be an improvement over the fabulous but dated MC2105. Recommendations would be greatly appreciated.

Many thanks,
John
