Power Conditioning done by IC's & Speaker Cables

Twl, you truly are a 'purist'. And in more ways than one. You are to be commended for some to many of your choices.

Audioengr: As i've stated before, there is nothing wrong with shielding a power cord. You've probably based your opinions of this matter on the commercially available models that are out there. I don't think that any of these do it "right", especially for high current devices like a power amp.

Other than that, i agree that power cords should be as low in inductance and series resistance as possible. If it sounds like i'm "dodging" specific design criteria, you are right. I am trying to say something ( as i have tried to do in the past ) without giving away the whole bag of marbles. Sean

TWL - I believe that the reason that you like the Bybee filters is because they eliminate some of the sibilants caused by wire in your IC's and speaker cables that has jumbled crystal lattice. If you replaced this with wire that has organized crystal structure, you could probably eliminate the filters.

This is the reason why so many folks believe that stranded wire is worse than solid wire. It's because cold-working the wire to braid or twist it into stranded bundles damages the crystal structure and sibilants are the result.

This is also why direct-immersion cryo damages the sound of the wire - the crystal structure is then helter-skelter, not well-organized. This causes reflections and current-bunching in the conductor.

Audioengr, so are you an advocate of single crystal wiring such as Harmonic Technology's, Acoustic Zen, Audience, etc.?

I ask because I have Harmonic Tech cabling (single crystal) in my system and when I removed my amplifier's in-line power conditioner and connected the 10 gauge 99.95% OFC romex to a cryo dipped Hubbell 20 amp IEC and plugged that into my amp, the most immediately noticable difference was the increase in sibilance.

I'd be interested to get your opinions on the results of my experiment?

Stehno -
I do believe that more organized, relaxed crystal structure can reduce sibilance. I actually just started offering a cable I call the "Perfect Crystal" (marketing talk), which eliminates most of the smll sibilance that my "standard" cables had. However, I'm sure that you can damage even single-crystal wire by working it or temp-shocking it. Single-crystal wire must be handled carefully after it is fabricated or you will wreck it. For instance, if you were to twist several small gauges of single-crystal into a stranded wire, working the metal like this would cause it to be no longer single-crystal. It would definitely break it up into smaller crystals, with the resulting sibilance.

It's hard to believe that crystal structure in a power cord would make much difference, particularly given that there is usually far more ROMEX in the wall that has relatively crappy crystal structure, but you evidently have the empirical evidence on this. I wonder how much of the sibilance reduction was actually due to the improved grounding or ground-filtering provided by the conditioner as opposed to the current-carrying wires? If the sibilance is due to ground-loop noise, then this could explain it. The power Hot and neutral wires do not really explain it, IMO. Another experiment, where you unground the amps at the wall outlets or at the conditioner using cheater plugs would tell you if it is a ground-loop causing the sibilance.
