Rick at Virtual Dynamics Cryogenically treats the 10 Gauge BX Armoured House wire. Here's the link to the product: Cryo'd BX Cable If the Cryo treatment has the same effect as it does on his other cables I'm sure you'll be quite happy at $3.50 a foot for the treated BX :) |
W, I resell Belden 83802 for dedicated lines ($2.50/ft first 25 ft, $2.25/ft above....) It's 2x12AWG tinned stranded (7x20AWG), in FEP, twisted pair in FULL shiield, then in a nice red, slippery, thin outer jacket. Threads easily through walls, and isn't too stiff. Fireproof, too. The shield twists up to a nice beefy 12AWG ground. Makes GREAT PCs, too, for which I assemble DIY Kits for $32 ea. RSVP your needs. This is VERY FINE commercial wire that performs admirably outright, and stupidly-good value. RSVP your needs. |
Use MC type cable. This is similar to BX/AC only it provides better EMI noise suppression and uses a dedicated grounding conductor. Run the grounding conductor to the ground bar of the main panel; NOT the neutral bar. If the panel does not have a seperate ground bar, any electrician can install it. It's also a relatively easy DIY. This cable doesn't cost a small fortune. Low impedance balanced interconnects are a must. RCA's will pick up the electric field radiated by the RF antenna and cause some serious humming. Consider a power conditioning shielded (isolation) transformer for your dedicated circuit. Use a 2.0 or 3.0 kVA. Your other circuits will pick up the elecric field and infect your system. This adds many degrees of isolation. Consider MIT power cables such as the Z-1 or Z-II. Yes, they dont have the heavy gage super-duper exotic copper and have molded rubber plugs - but they are probably the best in keeping out EMF/RFI noise, which sounds like your top priority. And, keep the cables (power and IC) as far away from each other as practical. Doubling the distance decreases noise by 6db. That's how I would go about it. Hope this helps. |
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 Cryoed 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 also think Gs5556 over the year’s gives excellent electrical advice. 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. |
