preamp for MOON W5,LINN Espek,Trivista 21 DAC


hello everyone,
I'm looking for a new preamp. I'm presently using a Bryston bp25 w/MPS-1. I'm looking for something with more body in the midrange. I've tried an Audio Research LS15. It had more body in the mids but it lacked the transparency of the Bryston. I'm looking for a transparent pre with richer mids. Any suggestions? Thanks
p.s. cables are MIT cvt350(pre/power),Apature rca(dac),diy cat5 speaker cables.
