Combating Stubborn Audio DIRT with D.R.R.T.
Dynamic Resolution Recovery Technology (D.R.R.T.) commonly delivers significant Improvements in the following areas of performance:
- Overall transparency
- Reduced noise levels resulting in a "blacker" background
- Channel Separation in Stereo & Multichannel Components
- Micro-dynamic detail with no increase in brightness or "edginess"
- Presentation and audibility of the component's intrinsic "sonic signature"
- Sound stage width, depth & height
- Imaging and instrument/voice localization
- Accuracy in the rendering of fine harmonic detail and tonal structure
- Reduced listening fatigue
- Realism & naturalness of the overall presentation
- Reliability and lifespan
Background Noise, "Hum" and/or "Hiss" Are Virtually Eliminated
We have all heard the common effects of electrically generated high frequency and 60Hz AC power noise that often emanates from audio systems to one degree or another. "Hiss" and "hum" are common annoyances, but fortunately the majority thereof can be traced to external causes such as poorly shielded cables, bad ground or signal contacts and/or ground loops, etc. In those cases the owner or user usually has the opportunity to address and remedy the problem by following established methods known to work in such cases. After all efforts have been expended in those efforts though, and proper corrections have been made, there often remains a residual level of noise that cannot be eliminated by any external means. That form of noise is actually being generated within the various internal components comprising the system, so the only way possible to reduce or eliminate it is to address and correct the underlying conditions and various sub-components from within a given component.
Therefore, first and one of the most important steps involving D.R.R.T. treatment is to properly shield and ground all component internal wiring and cables, which is almost never done by most manufacturers. As simple as this may sound, the task is quite labor and time intensive. Furthermore, with today's modern digital (DACs) and Class-D/Switching (PWM Power Amplifiers) components, from a technological standpoint the process is often not "simple" whatsoever either.
In those types of components in particular, we are actually dealing with extreme VHF & UHF Radio Frequencies (RF), and any engineer that knows anything about the field will tell you that RF Engineering can seem more of a "Black Art" than a science due to its extreme complexity. Something as seemingly simple as knowing which end of a given wire or cable's outer shield to connect to Ground can often be anything but "simple," such that if the wrong end is chosen the results can be worse and do more harm than had the thing just been left alone in the first place. Knowing such thins as "which end is which" is TDSS' area of expertise, with a special focus on Class-D/Switching Power Amplifiers.
"Caveat Emptor" (Buyer Beware): this type of work should never be undertaken by those that do not have good experience and knowledge of the field, or else matters CAN be made worse such that the component (again, particularly Class-D/Switching Amplifiers) can be made unstable to the point of self-destruction. One would be well advised to first check the credentials of any upgrade service provider before attempting modifications on these types of components.
The Component's Unique "Sonic Signature" Will Become More Audible and Evident
Regardless of design, it is THEORETICALLY IMPOSSIBLE for any component or device to reproduce a signal "perfectly" without (mostly) adding and/or subtracting (rarely) some small amount of information in the process. Generally, this effect is commonly referred to as the process of generating "distortion," with the bulk thereof being DIRECTLY RELATED TO THE DESIGN OF THE CIRCUITRY and the intrinsic electrical properties of the parts used therein. The total "profile" of the original signal PLUS all distortion artifacts then combine to yield what is commonly called the component's "Sonic Signature," and our D.R.R.T. DOES NOT AND CANNOT alter it whatsoever. In fact, by removing or greatly reducing the other forms of "audio dirt," D.R.R.T. will allow the Sonic Signature of your component to "shine through" and become more audible than ever.
Resolution and Retrieval of Extreme Low-Level Music Information Will Be Significantly Improved
For most, this area of improvement needs little explanation. Simple logic dictates that if one removes or greatly reduces the undesirable noise and distortion artifacts (audio DIRT) that work to cover up or "mask" the true micro-details that are contained in a given recording, then those details will naturally come to the forefront and become more audible. The exact same underlying process is at work here as in that of the Sonic Signature issue previously discussed.
Dynamic Performance and Transient "Speed" are Improved
This area of improved performance is primarily the result of the custom-built "ribbon-foil" cables that we use to replace some of the stock cables and/or wires inside the component being upgraded. Not all cables and wires are replaced with these custom cables because there are only a few key areas within the design of most any audio component where there is a real benefit to do so. Nevertheless, we are able to identify these areas and where appropriate, they replace them with our own custom cables.
