Background Noise, "Hum" and/or "Hiss" Are Virtually Eliminated (continued)
To a large degree, this area of concern is one of the main cornerstones of the TDSS D.R.R.T. treatment, as much effort is expended to properly shield and ground the internal wires and cables of a component. The noise generated by uch of today's modern digital components does not follow the common rules of proper grounding as they apply to components based on previous analog technology. When noise is pretty much limited in frequency to around 100KHz, effective grounding methods are relatively simple. Beyond that frequency range though, and things start getting a bit "squirrelly" and unpredictable. This even more so as the frequency increases, and to the point where you had better know what the heck you are doing before you go sticking your fingers inside somebody else's expensive piece of audio gear.
Having previously worked for almost a decade in the development in SOTA high power (40KW) switching amplifier tracking power supply technology in the engineering department of Crown International, we are well versed in the processes and techniques required to perform the task properly and effectively. While there are most certainly others that are cable of doing the same, few have a commensurate background in and passion for all things audio while also offering an audio equipment upgrade services the likes of TDSS.
Generally speaking, the application of proper shielding and grounding techniques to the interconnecting wires and cables within a given component can make a substantial improvement in sonic performance... and even product reliability. As a result one would be tempted to expect that such methods would already be employed by the manufacturer of the component during its assembly at the factory, Nevertheless, due to cost constraints resulting from targeted price points for a given product this is seldom the case - the main reason being that such techniques cannot easily be automated. Rather, the requisite manual labor is expensive and consequently avoided whenever possible. If reasonable product performance can be achieved without going to the effort, to the point that the product remains competitive in it class, then it will not be done.
In adjunct to the above, proper circuit board layout and general circuit design often reduces the need for application of extensive shielding and grounding within a product, at least to the degree that reasonably good performance can still be achieved without it. Again, as far as the manufacturer is concerned that is usually good enough, Then again, those methods alone never fully eliminate the underlying noise problems either. What few manufacturers realize is that "going the extra mile" to include it anyway can have a far more profound ability to further improve product performance than they would likely ever suspect. This is where our D.R.R.T. treatment comes in... and where you can benefit from better sound than what you might ever have guessed as well.
