You may not have the problem you think. The tube amp may have an input impedance near 500K which, compared with the others, is neglegable. I would suggest that you can call the sub manufactures and ask what impedances the sub amps are. If I remember correctly, my parts express plate amp was around 18k. A pair of 18k's in parallel is a manageable 9k. The tube amp's presence would then be hardly noticable if at all.
That said, I use a b-1 to avoid having a passive master volume control. Nelson Pass writes about the subjective sound this produces in his B-1 article.
My b-1 works great, adds litte or nothing I can detect and is not finicky to wire up. It is running constantly for several years w/o issues.
good luck.
