Extension power for ps audio p15


Ok, so recently I acquired a ps audio power plant 15. Awesome thing. However, I realized that there’s no configuration in which I can fit it into my cabinet with existing equipment. So I need to put it a few feet away at least from where my cabinet is. And all the power cords on my equipment are 3ft, they won’t reach the p15. 
I don’t want to spend all the extra cash to get new longer power cables. So what are my options? I can think of 1) audiophile grade power strips without all the power conditioning crap because the power coming out of the p15 is already pristine—say USD500 range; or 2) connect my existing Furman DM15 to the p15 and run my equipment off the furman—but I wonder whether the active behavior of the furman will degrade the power from the p15. 

What are the tradeoffs ?  What would you recommend?  Thank you. After breaking the proverbial bank on the p15 I’m loathe to spend a ton of money. 
Thanks very j much. Shankha

I just use Tripp Lite hospital grade  PS-615-HG-OEM with my Power Plant. They have a 15’ cord that I cut to the length needed. They are always on eBay.
I put my Core Power 1800 in back of my rack with the outlets facing up. This requires it to sit face down. Mfg said it's alright
 So far so good.
