Do any McIntosh preamps have non digital filter for bass and treble?

They also seem to have balanced outputs, which means they are really hybrids anyway.

Any model with 5 or 8 rotary EQ controls, whether preamp or integrated amp has analog domain circuitry. That’s C51, C52, and the current C55. The digital part is a slide in module, only a DAC, and has no EQ function.

edit:  these are EQ controls, not filters. The uppermost frequency is 10kHz, +/-12 dB. 

The C70 anniversary as well as the latest C22 models are promoted as all analog preamps. They both have tone control bypass switches for your convenience.

I'll be not helpful and say that my 1962 era MX110 and 1976 era MX113 both have analog treble filters. The MX113 sounds very modern too, albeit w/o any digital inputs whatsoever.
