Do HT enthusiasts pair processors with tube preamps?

Yes. Theta through VAC.
How many threads do you need to start in multiple forums regarding this? Supposedly you have a NAD through a Schiit and running your multichannel Mac amp in 2 channel only.  What are your center and surrounds btw?

IMO, Changing your tubed pre to a high end one won’t do much for your overall HT experience.  Separating your HT from a 2-channel setup would be best. If your focus is on HT, then just get a better pre/pro

Kmmd,
like many, full integration of ht and 2 channel is ideal. Separating systems rec, not helpful.

oh, vac is awesome but remote is not fully functional. No input control.  Otherwise would get it. Guess i am strange this way.  Looking at vtl 7.5 pre but out of production for a few months.  Part, labor issues.

You need a preamplifier with "processor bypass" mode, like the Classe CP-700, which is a solid state amp, but applies here. This allows me to send my fully balanced analog stereo signal from the player straight to the preamp.

Thanks, but doesnt added preamp impact sound?  Which can be a good thing.
