The Shunyata will help some but it wont fully realize its potential without clean, consistent power. Have you looked into dedicated lines or a separate AC Regenerator?
And as for budgets, even though mine was small compared to my original system its still orders of magnitudes more than what "normal" people would pay for a stereo! LOL! Gotta love this hobby.
BTW, Portland is a great place. I lived up there when I was much smaller but to this day I remember the lush, green scenery.
