Are you sure? Based on Questyle tech. description, the M15c uses dual Cirrus Logic DAC chips, whereas the M15i uses a single ESS DAC chip.
That would be a little more than a different tuning…
Yes it has a different DAC, with the same amplification modules and a slightly different PCB layout. In use though, it's the same size and with the same outputs and gain switch as the M15i, just sounds different.

I briefly had the M15C and was unimpressed. Not that it was a bad unit but not excellent either. Just kind of in the pack.
