When I had my 750 MCX monos several years ago (before I went all tubes) I was using an Audio research Ref 2 Mk ll preamp and never used any DC bypass caps. I had no problems whatsoever.
All tube preamps don't leak DC. Just the poorly built ones do. I have used a few tube preamps with my 700c without adding a DC block.
