I do not use a BAT pre simply because the mc. c48 is a all in one solution and was a big step up from the older arc ls2b I was using previously.
I considered BAT pre of course but the c48 let me get rid of 2 other boxes and simplfy matters. it has 4 digital inputs, mm and mc inputs and a headphone output so i could get rid of my phono stage, headphone amp and run the vault straight into the c48.

TBH I am not really asking if I will like it or not, that is obviously all up to the individual and their system but rather just others views who have gone this route from possibly years of ss or tube power amps.
One thing I may do as I have a nuforce multi channel amp in the ht rig is pull it and install in the stereo just to see. would mean running rca connects but could be a worthwhile test......
