Thx for the suggestions and replies!
Coming from an "audiophool" background, one std. practice I use is the use multiple line conditioners.
Even for non-audio equip. (computers, etc) , I think power cond. makes a difference in operation and reliability. So, fewer HDD crashes/failures, fewer computer lock-ups or freeze-ups.
My layered approach to pwr cond:
Chang Lightspeed --> APC UPS --> Tripp-Lite Isobar.
Also, I use a fair amount of ferrite beads.
