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

The answer is that McIntosh made hi-fi gear before there was digital, so yes. Not sure about current models.

If you want analog bass and treble, look for something by McIntosh built in the 70’s or 80’s. What is your problem with the digital bass and treble?  It is much cleaner sounding and the controls are made for small tweaks in the sound. 

Naw, I mean recent models. I am sensitive to sound filters. If I wanted to go down that route, I would just get a class D. At least the MA12000 is still analog for the treble/bass. 

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.
