PC or Line Conditioner

Hello,
Quite a few years ago I had a post asking people to chime in on what they would recommend for a good Power Cable. I find it funny because at the time I had the Ayre CX-7xe CD player, V-5xe Amp, and the K-5xe pre-amp. Now I have the V-5xe (in Black), K-5xeMP, and the Oppo UDP-205, using AQ Wind XLR IC's. I still have (2) Richard Gray's Power Company PC's and the RGPC-400 Pro. I find myself in need of more outlets and was looking at a used RGPC off of Ebay, but after talking with Gary, the tech guy, at Ayre he really believes that I should spend the money for the Ayre L-5xe that has (4) outlets. There is one right now on Agon for $1,400 OBO. It is not a conditioner in the normal sense, it is completely passive and there is no voltage regeneration or current limitation.
But I still am a fan of running a better PC than what comes with the component. Like I said I have the (2) RGPC cables and I just bought a Kimber Kable PK-14 Ascent. I would really like to keep the price for the cable under $500 but I also am giving more thought to putting that $500 to the Ayre L-5xe instead. All though I would be looking at more than twice what I would be spending on a Power Cable.
Any thoughts would be greatly appreciated!
Thanks,
David
