Power Cord & Power Conditioner Recommendations

Something more for consideration:
Isotek Evo3 Aquarius with Shunyata Venom HC (v1 or 2).
The Aquarius made a big difference in my system with the as supplied Premium cord.
Replacing it with a Venom HC v1 brought further improvement.

Awesome thanks for all the info - so it seems all things considered the fact that I have an older house plus the cost / benefit realities would make power conditioning the priority for sound quality and equipment protection - then budget for power cords later. With the 2 powered subs in the tritons plus all other components I will need 5 power cords which is too expensive for me to buy all at once along with the conditioning. Would the conditioner be a product I should buy new (typically I buy demo equipment) to have an equipment protection warranty, etc.? Also assuming the blue book value of the components totals 12k or so what be a reasonable price cap for the conditioner?

Here is additional information to consider that recently came out.

Very interesting video - now I can't tell if I'm more or less confused. Is there a valid rebuttal to this?  

Me thinks you need to educate yourself on the different types of power conditioners. There are passive and active conditioners. Then there are power regenerators which PS Audio is known for. Also, not all PC's have surge protection. That's what's found on most power strips and protects your gear during power spikes. 

Lots of info in the archives:
