I've received a few PMs asking me what PC I am using for "high current" (i.e. power amp) applications since I'm a devotee of the Ching Chengs for low power level gear.
After much experimentation, I've chosen a pretty conventional custom cable design comprising of Furutech 4.1 DPS cable with Furutech plain Jane FI-11 copper male ends and gold FI-28 IEC connectors. As I have said previously, I think the choice of connectors should take the receptacles they are used with into account. In my case, the cables go into Shunyata CopperConn AC wall outlets (finally recently released commercially!) and gold IEC contacts in my Soulution gear.
The cables are fabricated by our own Dave C at Zen Wave Audio. I use Dave because in communicating with him privately, he showed me some of his custom home made electronics with some of the most beautiful wood case work I have seen. This told me all I needed to know about his craftsmanship and in addition, his prices for the cable components plus assembly are extremely fair.
In an ideal world, possibly. But honestly, I think I'm at the point of "if it ain't broke, don't fix it". I've spend more hours listening to PCs and countless types of outlets than I care to think about. I'm happy with that aspect of my system so no plans to experiment further.
Francisco and David,
Everyone has their own interpretation and meaning of descriptors like "neutral". The better term for the Ching Cheng is "natural", that is, it conveys the timbre and tonality of instruments in a manner that sounds as one would expect from the real instrument. This is totally subjective of course. When one uses the term "neutral" as it relates to frequency, that's more easily understood in terms of bandwidth measurement. To me, it suggests the bandwidth is not rolled off or exaggerated at any particular part of the spectrum. If we took objective measurements of the frequency response of just about any power cable, they would probably all measure essentially the same; that is, "flat" in the audio range, until we got out into extremes of sub megahertz frequencies, or frequencies approaching DC. But they may all of course, sound different. Part of that sonic difference may be the way they handle instant high power conduction. When I refer to response to high current demands, particularly for the lower register, I find the impact or weight of the CC's is a tiny bit less than the PC I use on my amps. It's not a dimunition of bass level per se, but rather a slight limitation of the dynamic impact of bass transients that at high volume, can translate to over 500 watts of peak power output in some amplifiers. So yes, in that case (my amps deliver 1.1 KW into a 4 ohm load and 6 KW at peak!!), I think the Furutech DPS 4.1 performs more satisfactorily than the Ching Chengs. But at low power levels, such as phono stages , DACs, or servers? Those signals are not translated to massive current delivery in front end gear, and so I find no reason to move away from the CC's which are just beautifully natural sounding and therefore highly pleasing. Could a huge monster PC be just as satisfying in those applications? Perhaps, but as I've said, I have no interest in exploring that at the moment.
