best pre/amp tube combo for under 3500?

I have energy veritas 2.3 speakers, well tempered classic with black platter and tone arm, cary 303/100 cd player and a plinius 8200m2 amp. I'm interested in upgrading to tube separates for a warmer sound. The pre I'm considering the most is an audible illusion 3a and the amp is a conrad johnson primier 11a. I might jump up to the primier 12. Also the Audio research 100 monos. All advice regarding individual components and how they work together is greatly apprciated.
