Of course they do offer integrated amplifiers that have MC input preamp, just that they don't seem interested in competing with Marantz (looking after their little brother I guess) in the Americas, here's just one example:
SoundStage! Hi-Fi | SoundStageHiFi.com - The Best of the Tokyo International Audio Show 2019
The PMA-SX1 Limited is a big, beautifully built, exquisitely styled integrated amp capable of outputting up to 50Wpc into 8 ohms or 100Wpc into 4 ohms. On its rear panel are one set of balanced (XLR) and four sets of single-ended (RCA) line-level inputs, and two more sets of single-ended (RCA) inputs for the built-in moving-magnet and moving-coil phono stages.
For only about US $6,000 (BEFORE Tariff, so...)
You do get as much as
50 WPC, 2 channel driven stereo, but "high current" capable lol.. If one wants their less power output integrated, one could opt for their lower models in the PMA line, Gene reviewed one of those lower end product and seem to like it, I don't remember if their have MC input, probably not, as those seemed to be listed for under $3,000.
