mcintosh mc1201,what preamp?

i just sold all of my mcintosh gear except the xrt22 speakers & im starting over,the amps have been replaced with mc1201 monoblocks & the preamp has been replaced with a c39 that i'll use as a temp until i can find the perfect pre for the big mono's.
i accidently hit enter & posted this before i finished.

i dont have a preference of tube or solid state & i would like to stay near 4k but i can sqeeze 5k if needed,i would love to hear from other high power monoblock owners to see what they are running.

ive allready tried the mcintosh c2200 tube pre & i would like somthing a little darker sounding.
