Power Cord Advice


I have the following amps in my system, Acurus A250, A200, and A150. Would I realize a noticeable improvement in sound and dynamics with higher quality power cords. Also do other components in my system need upgraded power cords or just the amps. Thank you so much for your help. Rick

Kacz, wanted to clarify that my house wiring is not stranded, but is solid core, similar to Romex, not sure the brand. It is only 12 gauge times 3, however, and all the breakers are only 15 amp. We only have 200 amp power service, also. I don't think this is as much of a drawback as has been made by others, however. Also, I must take issue with your assumption that high quality or "new" cables in your house, or breaker box, would TOTALLY eliminate the need for ANY filtering or conditioning, especially for line level/source components. I feel that there is no such thing as a clean 60 Hz sinewave straight from the power lines (or under-ground lines). Just look at the test of the PS Audio unit, and you'll see how distorted the waveform was before it got to the PS Audio. I've considered trying one, but I think it'll consume too much power for one of my rooms (700 watts?), where both source and amp are on the same circuit. That said, I have every intention of trying your cord both on my source, and on both my Krell and Rogue amps. I like to plug my source components into a Chang Lightspeed 6400. I'll try it with and without the Chang, for argument's sake, though. I have the Z-Cord 2, and believe that it is a 14 gauge times 3, is it not? It has the stock connectors, and since it has beaten EVERY expensive cord I've thrown at it (when used ONLY with the source component), I'm not inclined at all to change the connectors, fearing a loss of synergy (I realize many enjoy doing this, however).............I've noticed that Purist Audio Design, and also ESP, use the Eagle IEC connectors. Do you have an opinion on them, Kacz?..................As far as "tweak freaks" go, I would say that I am NOT really in that camp. There are those that believe that interconnects and speaker wires should have conductors literally exposed to the air with no dielectric or insulation, and that speakers should have no binding posts, that the wires would just come out of a hole in the back of the cabinet, and even soldered directly into the amplifier (bypass its posts), when possible. I admit that binding posts have a sonic signature much greater than the "wire" connected to them, but there are certain safety and practicality issues that should be adhered to to avoid all sorts of time over-consumption and terrible "accidents", it seems to me.
To Sol (the name of our sun, but I guess you know that): No, I haven't experienced directionality issues with regards to in-wall wiring, but I haven't experimented with it, either. I don't foresee changing the house wiring in the house I'm in now, but plan to make you all envious with what I'll do in my "dream house" one day. One thing I would do is use several parallel runs of large gauge wire for each circuit, and perhaps anywhere from 20 to 40 amp dedicated circuits (among other things)...........To Nhorton: You must have missed my epic saga called "My Sidewinder AC cord Progress". Seek it out, it's under either "Sound Advice", or "System Matching", I forget which. As others have done, you can even highlight, copy, and paste anything relevant you might find, in another thread, like this one for example.
FBI....Yes, I better do as you say, or I'd really be stupid, wouldn't I?.............Regarding conductor size, my experience has been that large AWG does indeed make the most difference with power amps, and that is a given. Of course they are the most current hungry components in anybody's system, so less DC resistance in a power cable will always allow more current to be transferred. However, I did experience many improvements, including dynamics and bass weight/extension, when I went from the stock 16x3 cord on my CD player, to the 14x3 MIT one. Interestingly, dynamics didn't improve much more with all the larger cords I tried with the CD player.
