PC & Dedicated Power Lines Questions

I'm about ready to upgrade my powerlines with dedicated 10awg 20A runs. To see what's in my system, click "system". I have just added a Shunyata Hydra 8, but haven't upgraded it's power cord yet (thought I'd make my own). A little background, I'm a electronic tech and I work on big servo looped systems (CNC mills, stretch presses that are analog feedback). So I know how important it is for good cableing with no noise. Most my power cords are DIY with either 10AWG wire or beldon 83803 with Oyaide P/C-79 connectors. My amps still have the OEM cords for now untill I get my incoming power straightened out.
Question 1) I was going to add 3 incoming lines with 10AWG wire on 20A curcuits off of the same leg or phase. One for each mono amp (might add my soround amps on them too) and a third to power all the front end stuff including a TV. Is this overkill? Should I just plug the hydra in my already supplied 15A line (it has a pass-Seymour outlet) and just add dedicated power for my amps?
Question 2) Power Cords. I just can't beleave the cost of these!! I can get hi quality fine strand 10awg copper twisted 4 conductor cable for free. I also have a bunch of 5 cond 16awg twisted with sheild. I was tempted to make power cords for my amps and Hydra from this and I have made some power strips already with Oyaide and Pass & Seymour outlets (see my system for pic under Oyaide). The Beldon 83803 is a PITA to work with and in my field it is considered cheap cable. I'm suriosly looking at VH Audio Flavor 4 DIY cords with Oyaide connectors. Flovor 4 for amps and Flavor 2 fro my Preamp. I have a sheilded beldon on my CD player now. What are your thoughts?? What PC cord should I use for the Hydra, was going to buy a used Shunyata Python Alpha, but just thinking of making a flavor 4 for it? Sorry for the long post but am curious to opinions. Thanks.

Another vote for dedicated lines, first. That has been my experience as well. As said so well (above) dedicated lines are a basic correction to so many anomalies. Then try whatever else interests you in the way of power cords and conditioners.

Happy (regulated) Listening!

I've always agreed with the dedicated lines, but now I wonder what to run as a conductor. The Oflex mentioned above?? I have enough for one run it has a braid sheild and 4 16 AWG conductors with a GND. # 16 is rated @ 10 Amps so I could double them up, (one outlet) and by code you can downsize your ground. This could be for the digital. I can get 10 AWG romex from VH audio that looks just like what Cardus sells. Or just romex from home depot. I do have some 12 AWG (twisted) in metal flex conduit left over from wiring up my shop?? It's going to be a bitch to feed that up from by basement walls ito the wall upstairs.

Dedicated lines are it-without a doubt. The Hydra will still be great for either your pre or digital- just experiment for optimum benefit. Dedicated lines, which I have used for 20+ years, do not replace good power conditioning in my experience.

The Hydra is a unique conditioner, it really doesn't have much in circuitry inside it. I know it uses MOV's and it's made in the beutifull state of WA where I live. We have lots of wind storms in the winter sometimes causing major power bumps and sags and outages. I lost my power for almost a week last year. So I hate to have all that $$ gear just plugged in the wall. But we'll see. So are running the Oflex cable in your walls?? I'm curious now if this cable might be a good idea to try. I have about 20' of it now. I'm off all week but when I return to work I'm going to check around and if I can find some laying around.

Here is some information from one of my posts on Audiogon (another similar topic).

“I have experimented over the last 6 months with various wires to use for dedicated 20-amp circuits. I have the following wire in use in no special order:
1) 10 gage Romex
2) 10 gage UV
3) Belden 83802
4) Virtual Dynamics 10 gage BX Cryogenically treated with Cryo’d circuit breaker. *

I have not tried the following but I’m sure it works, 10 gage solid THHN (white/black/green) manually (electric drill) spiral twist and snake through conduit.

To my ears on my revealing system I hear NO difference between (1-4)! I think simply using a dedicated circuit with 10 gage copper makes the biggest difference.

I hope all that read this find it helpful, it’s cost me about $500 (out of my own pocket) to complete the testing for my own peace of mind.

* There might be other positive factors to using cryogenically treated wiring besides sonics. It might lower the operating temperature of equipment.
