Well, the gear listed is the result of budget limitations and not sound. Aside from the sub, that was put together on a budget as well, everything cost under $50 and most around $10-20. Still, I've too much more stuff stashed around here or out on loan, but this equipment suites my preferences best.
As to the HPMs, well, even after modification, they probably won't be to my taste. Then what? I'll have yet another pair of bookshelf speakers and not a place for them, so off they'll go to someone who does have need of them and maybe I'll have the cash to fix up my Fisher 100-T tubed pre-amp/tuner (rectifier is a true fire bottle thanks to bad caps) and Dynaco SCA-35 (possibly bad power tranny). Oh, so yes, I do have some tubed gear, nothing near so good as your 300Bs.
