As far as i know, the signal coming out of the transport that feeds the DAC is centered at 2.822 MHz. This is an RF ( Radio Frequency ) signal. The data is super-imposed or "modulated" on top of the RF signal, much like someone's voice is transmitted over radio waves.
Having said that, other signals can be super-imposed or "sneak into" the RF signal ( technically called a "carrier" ) that is carrying the data that was decoded from the disc. Filtering out extraneous garbage, such as other radio waves ( RFI ) that could be using the AC line as an antenna, might make quite a bit of difference in such a case. As i've mentioned before, the more effect a power cord has on a component, the poorer the components power supply and filtering was designed.
Taking the above into consideration, rather than spending hundreds ( if not thousands ) of dollars on fancy wire, why not correct the original problem ( poor filtering within the component ) by doing some simple and FAR less costly modifications to the unit itself ? While i know that "fancy cables" add a lot of "prestige" to a system in terms of being able to drop names, etc..., they are nothing more than a phenomenally priced band-aid for what was a lack of engineering to begin with. This is not to say that i don't use "fancy cables" in my systems, it's just that i don't pay hundreds of dollars for them nor do i expect them to solve fundamental problems that are pre-existing within the system itself.
As far as price goes, good parts and engineering are not cheap. Then again, they are not THAT expensive. One can literally take a run of the mill product with good basic design, throw $100 - $200 worth of raw high grade parts into it and walk away from competing products costing much, much more money. What do you think that all of these "tweak guru's" are doing ? They are simply swapping parts or putting in "extra" parts that the "cut corner" factory production left out to begin with. It's not hard to read values and perform direct substitutions, yet people think that most "modifiers" work "magic". They don't do anything different than what you can do if you put your mind to it.
Why do you think that DIY is getting so big ??? People are finally beginning to realize that they AREN'T getting what they paid for in "high end" audio and are trying to do it themselves. Hell, even Nelson Pass has his own
DIY website, contributes to
DIY Audio.com AND writes articles for a DIY magazine named
Audio Xpress. Nelson knows where the market is going and wants to stay in touch with it. He also knows that DIY is not that hard to do and it is a HELLUVA lot of fun. Sean
