Hi...i re-read your post a few times. i think you can do a few things:
1. CJ tube preamps have HT passthru...no doubt others do as well.
2. You can run the sub from your CJ preamp which usually has 2 sets of RCA outs...1 to amp and the other to sub
What you may not be able to do without some constant changes:
1. Use 2 different amps for your fronts. If you wish to use tube pre/tube amp for 2-channel...then unless you disconnect the tube amp from your fronts...you will end up driving them via your tube amp...no?
The good news is if you do the math...average tube life is 3,000-5,000 hours...some more, some less. That is a few years of use...and further if you add up how many hours of movie watching you do a week and multiple by 52...you probably are not shortening the years of use by that much.
In the end, for the sound quality, and convenience...you may just decide to enjoy your tube equipment!
