Let me explain, as simply as I can: as audiophiles we try different components to improve the sound of our systems. Whether they are changing the speakers, the amplifiers, the source equipment, cables, adding grounding boxes or upgrading the power delivery infrastructure. All those changes have very limited capacity, by design. The reason for that is that electrical power systems and high-fidelity/high-end audio components are designed to tight tolerances. To give you an example that you can relate to, you don’t want the power mains to deviate more than +/- 10%. In well designed and executed audio components, you don’t want the frequency response to deviate by more than 1 dB from 20Hz to 20KHz. At most you want to limit the deviation to 3dB during the audio frequency range to be a well designed and executed neutral component. So you are by definition bound by the design of each component. The problem is as you start to link each component together each connection forms a RLC filter from the source component’s output impedance, the interconnecting cables’ electrical characteristics, and the next, down the audio chain, component’s input impedance. This is why all systems sound different and different system configurations sound different. As you assemble a system you are stuck with the static frequency alterations inherent to that the system’s make-up.
As changes are made to the system’s make-up through component substitutions, the resultant frequency response of the overall system is altered. And this is why we hear a change in the sound when we make a change to the system. These changes are unpredictable, to a large degree but you can actually do the math & electrical analysis or model the system in software to predict the change if you are so inclined, and worse they are static; so you get a different sound that improves something’s in some cases at the expense of other things, in terms of sound quality. The changes brought about by these trial & error component substitutions are limited, or what I call “residual”, because as stated above, if they are well designed and executed they must be neutral and adhere to tight tolerances from their nominal specifications.
With the above in mind of the limited capacity to influence the overall sound with well designed and executed audio components, how do you make impactful changes to the overall sound of the system? How do you restore tonality or neutrality caused by the inherent string of RLC filters embedded in the system? How do you make changes to the sound of the system that don’t add noise or add static “equalizer” type shifts in frequency response?
Around 27 years ago, I noticed that two different copies of the same CD’s sounded drastically different to me in terms of sound quality. I also noticed this with LP’s of the same recordings. The differences were that the recording in all cases had been remastered, some times for the better but often for the worse. The changes that I heard in either cases where more drastic than the changes that I had managed to achieve with my amplifier, preamplifier, source components, speakers, cables substitutions that I had been making, following the Audiophile “upgrading” process.
My scientific, engineering, and intellectual curiosity got a hold of me. I then went on a 7 year deep dive into exploring and understanding the world of high-end mastering studios. What I learned from that experience and education changed my entire perspective of home audio reproduction and the audiophile pursuit.
With my gained knowledge, I assembled two of the most powerful mastering systems in the world and successfully was able to surgically change not only the sound of recordings but ultimately, with the “system-Remastering” process, the inherent sound of systems.
I will pause here for questions. More to follow if there is interest. Please reference my thread linked below for additional details:
