Are Their any Tube Preamp with Home Theater Bypass?

To name a few,

ARC REF 6SE & LS28SE

Modwright LS300 & LS 36.5 Tube Linestage

Backert Labs Rhythm & Rhumba

IME, you’re better off keeping 2-ch and home theater separate. Can it work, sure but the end results can be very mid-fi on either side. If you’re striving for ultimate performance in both arenas, keep them apart. Been there, done that with ARC / Modwright on 2 ch and Classe Delta Series / Krell Evolution Processor and Amps on HT - 7.2 driving all B&W 800D2/HTM/804D/SCMS/JL Audio f212v2. 

Conrad Johnson.   And no , not any preamp will work if you want it to sound half way decent.   The proper HT bypass eliminates the volume , the input is unity gain

The receiver or HT pre pro is the master volume when watching video. 

I agree about keeping them separate but that’s not always practical or possible 

@audiotroy , thanks for the work around and everyone else thanks for the suggestions
