What are the power cords: brand, material composition, gauge, etc.?

I had extension cords I made myself...3 conductor 12 guage, SJ 300 V. AIW-K SCA FT1. I used regular top grade plugs that was recommended to me from a large electrical supply house. I chopped the ends and installed the OYAIDE C-046, and P-046 on the ends.. Wow!! I suppose if I use that OYAIDE silver wire between them it would sound better, but I found that the wire has far less influence on the sound than do the plugs
I have a bunch of different wire and a couple of powerYou used
these in their stock configuration, correct? In other words, you didn't replace
plugs on a Cardas cable with different plugs?
Just trying to understand how you concluded plugs make more difference
Is it based on the extension cord sounding better than the Cardas,
etc. after you had installed the Oyaide plugs?
Wonder what would happen if one put Oyaide plugs on Cardas wire...
BTW, a local dealer is very enthusiastic about the Oyaide power cords. I use
Oyaide PA-02 wire for 30 foot balanced interconnects, and it is excellent
wire. You can find the various Oyaide wire, including the power cord wire, in
bulk from a few retailers.
Actually, I found Cardas power cords the very worst power cords I have ever heard. Yes I chopped the ends off of Purist, Audioquest, Cardas, and they all very much improved with the Oyaide plugs, and they all sounded pretty much alike. I like best the wire that I got from the electrical supply house. I may try the Oyaide wire. I believe that is 10 guage to the 12 guage I'm using, and has an additional ground/shield. As it happens my system is DEAD quiet with this wire.
I installed a pair of Oyaide Tunami GPX power cords on my amps today. The short story is more clarity and a lower noise floor which has resulted in more apparent volume at a lower setting on the preamp's volume knob.
They seem very transparent (meaning neutral), as I also discovered using Oyaide PA-02 wire for balanced interconnects between my preamp and amplifiers. I'd say there is a definite "house sound" between the two examples of Oyaide products I own. Crisp and clear with excellent tonal balance. Akin to Shunyata in that regard.
I have a 1.5 m length of Oyaide Tunami I bought from
VH Audio terminated with Oyaide p/c-004 plugs i also purchased there, you can see pics here;
The drop in noise floor was so dramatic I had to adjust my volume setting and panicked I had screwed up the attachment some how causing a drop in volume level somehow,lol.. It was a rather startling and obvious change from the
pre-fabbed stock cable I'd had. Mating it with their R1 may have had something to do with the overall success of the effort but I am very satisfied.
I have also been experimenting with Oyaide plugs and IECs -- replacing the stock plugs and IECs on the ends of Synergistic Research Master Couplers. The effect has been nothing short of astonishing especially with the P-004 and C-004. Resolution, dynamics, sound stage have all improved dramatically. I see that SR actually uses an Oyaide P-079 on the end of one or 2 of their high end cables. Actually I have found the P-79 veiled and constricted the sound and the P-004 opened everything up and took the veil off with the Master Couplers -- this was on a special purpose cable from a 100-volt amp to a step-down transformer. But I imagine Ted Denney at SR knows what he is doing with the cables he is terminating with Oyaide plugs. He is one of the most knowledgeable people in the high end audio business -- IMHO.
Update: Regarding my earlier posting about the P-079 I changed things around. I cut the stock plug off the step-down transformer and spliced it on the end -- the result was dramatic. The transformer now leads via a Master Coupler to a 100-volt Marantz PM-15 (original 1994 version) integrated amplifier. I took the stock plugs off the Master Coupler and spliced on an Oyaide C-004 IEC and P-037 -- a dramatic improvement, once again. If you experiment with low cost SR Master Couplers and high cost Oyaides you may find a perfect match for your system. It is all about synergy. You will notice an immediate difference in resolution (so much more low level detail), bass and sound stage.
