The mac tube preamps are quite good and have a ton of features (DAC2 bal, RCA nputs etc). MC275 is a mediocre tube amp IMO, I owned one and sold it after trying one of their SS amps. I ran a c2700 and MC275 for a while then switched to the MC301 mono blocks. The MC301’s were a big step up from the MC275 which I felt lacked in many areas that make tube amps great. Sounded more like a SS amp with crappy bass then a tube amp.
If it was me, I would get a used C2700 tube preamp and a SS amp to match. Or a hybrid integrated. I’m personally not a fan of the Prima luna stuff after a few friends owned them, ok for the price but the BAT gear will be better imo.
