PC or Line Conditioner

@f1wheels, First off as others have insinuated, I'd like to know if you have any dedicated AC lines from your electric panel, (and do you use any higher end AC outlets) to your system and if so how many?
Also what size wire and breaker feeds your system?
I realize this does not answer your question but it's important to know first.

Hi David,Have you ever thought of making your own power cord. I have and it saved me a fortune. As I live in the UK model no's and prices will obviously be different but to give you a ball park figure I recon I spent about
£540.00 on the supplies so what I have for that is ,
Neotech NEP-3001 III Mains Power Cable
Furutech FI-32M Rhodium Power Plug
IeGO Gold-Plated IEC Connector
SR Blue Fuse.
I have tried the cable in a comparison with a JPS Kaptovator at three times the price of the lead I made up and to also let you know I also put it through the  Ayre L-5xe  and I swapped between both cables. Now I do have to say that I waited a couple of weeks before I did the comparoson so the new cable would be burnt in . I put a Dab signal through a spare system I have in a work shed 24/7 for the fortnight before i was ready to compare. The difference I found between the two cables was so minimal that I certainly will not be buying mains cables at The JPS prices again. The only thing I did have an issue with was that the cable is very thick and stiff so it is sore on the fingers and you need to get plugs that can accept that thicknes of cable. If you are fortunate like I was you'll get a supplier who'll look into these issues and keep you right. If you try it and like it The  Neotech NEP-3001 III Mains Power Cable is super for making a dedicated spur just for your Hi Fi .
Whatever you decide to do good luck.
Regards Jim.

Hello,
First off Thanks for all of your replies! As for my house it was built in 2001 and I am located fairly close to Seattle (about 30 miles South). From what I can tell by looking at the breaker box I have the standard 15 Amp breakers in my front room. I did however installed two silver plated, cryogenic treated hospital grade outlets on each side of where all my equipment is. There is no way for me to run a dedicated line as I would be looking at tearing down a bunch of sheet rock.
Once I do my cap upgrade on my Thiel 2.4's I will try the main amp plugged into the Richard Gray's 400 Pro and then I will try it straight out of the wall. To my knowledge I believe he went out of business, all though you can still get his PC's on Amazon. But I only see his AC Conditioners, used on Ebay or here on Agon. I can also try switching between the Kimber and RGPC cables to see if I can hear any different. At the time I purchased the RGPC cables they were running right around $450 a Meter if my memory serves me correctly.
Thanks Again for your input,
David

OK, so no dedicated lines. Are you using any lighting dimmers on your first floor that introduce noise? I'm thinking that maybe you could move electrical devices from the shared line to a different breaker.

In any event, another passive conditioner is the way to go, not a new PC.

In your scenario, I recommend you purchase a balanced power supply, such as the Core Power Technologies Equi=Core 1200 or 1800 or the Equi=Tech 2Q (although the Equi=Tech company makes a variety of units to choose from).
I'm not familiar with the Ayre L-5xe, therefore, I don't know how well it would clean your AC power. You did mention that your were in need of aditional outlets.
