tube preamp for mcintosh solid state amp

Anyone drive a mcintosh solid state amp (402, 252 etc) with a non mcintosh tube preamp. If so, what combination and what results
Before moving away from mac amps I was using an Audible Illusions Mod3a with great results. I had a MC7270, MC352, and a MC402 in the mix at one time or another. The AI worked really well with the Mac's...
I am driving my 402 with an Audio Research LS26 and would like to upgrade to a REF3 or maybe consider the McIntosh C500t but I am currently enjoying the economy too much! So LS26 it is, and very happy with it.
