The perception of time, like audio, is subjective. Our sense of time’s passage varies dramatically throughout our lives. Think back to when you were in grade school, tossing and turning in your beds between Thanksgiving and Christmas in anticipation of Santa’s toys—that was excruciating. Now think back three years and how quickly that time has passed. And just as our perception of time shifts throughout our lives and even differs from person to person, so too does our appreciation of sound quality differ from person to person while escaping any meaningful objective unifying correlation.

In order to feel in control, we attempt to reduce subjective phenomena to objective measurements: seconds, minutes, and hours for time; frequency response, distortion figures, and signal-to-noise ratios for audio. However, these metrics ultimately serve to improve subjective outcomes rather than existing for their own sake.

It’s crucial to recognize that no two individuals perceive time or sound identically. What constitutes high-fidelity audio for one listener may be unsatisfying to another. What seems like a long time to one can seem like a brief moment to someone else. This variability in perception extends beyond personal preference. Fundamental differences in human perception are at their core subjective and so defy any objective universal definition.

In essence, both time and audio quality exist at the intersection of measurable phenomena and individual experience. The way we experience sound and time blends the objective with personal feelings which are subjective. It is the intention behind all human endeavors, especially those that center around personal enjoyment, that create the final outcome. This is what keeps scientists and thinkers locked in the never-ending dance of innovation and progress in service to human subjectivity.IMG_8017.jpeg

Nice narrative on the perception of time and any sensorial perception, that are different, but sometimes connected, concepts.

Can I ask you a simple question - excluding the very relevant involvement of science in technology, do you see any new recent science effort in current stereo sound reproduction?

Yes, I do. Personally, I use McIntosh electronics, not because I think they’re the best—clearly, they’re not—but because they ideally split the difference between tube and solid state. Especially their “expensive” two-box valve preamp and their 611 mono blocks; they’re good enough to create a state-of-the-art stereo if everything else is dialed in properly. They are essentially the Chevy LS V8 of audio.

To my way of thinking, and from my experience, the greatest ROI comes from focusing on areas that are either taken for granted or are completely new and have not yet been considered by the majority of manufacturers, if any at all. These areas include:

• Electromagnetic management around components
• Electromagnetic interaction around cables
• Using disparate electromagnetic fields to condition AC and ground
• ULF biasing of transmission lines and circuits, as well as the room as a whole
• Applying these technologies that we collectively refer to as UEF Tech (Uniform Energy Field) to legacy products like Ethernet switches, routers, power and ground conditioners, and servers

This approach nets massive ROI, whereas spending significantly more to refine legacy technologies for shinier, fancier boxes only nets incremental performance gains at near-exponential pricing increases, resulting in significantly less ROI.

Agree about time and hearing, but this post is the clearest explanation of your aims that I've seen and is worth highlighting somehow. Which, of course, would lead to questions about how identifies (if that is possible) electromagnetic fields and interactions.

It also leads to the question about whether you are looking to achieve a certain sound (you mentioned the split-the-difference McIntosh gear) or do you judge success by musical involvement. I ask because your UEF switch (current model) seems to remove noise but not mess with the listener's position regarding the soundstage (for example, closer to the performers). Likewise, the SR grounding block that is still settling in. That may just be how I hear it.

Taking my woman out for a date, so I’ll make this quick. As an audio designer, it’s my job to build cables, accessories, and electronics that allow all dogs to hunt, if you know what I mean. McIntosh splits the difference between tube and solid state, and it even enables you to use a tube preamp with a solid-state amp with perfect impedance matching between the two. If I designed on Audio Research, I would skew in one direction. Conversely, if I designed on Soulution, I would skew in the other direction. When we design on McIntosh, and given our voicing options that we build into most of our products, we work in virtually all systems.

Tomorrow we can talk if you’re interested in what I personally prize, but ultimately, I engineer and voice for maximum resolution without sounding fatiguing, and give people the opportunity through tuning options to dial back resolution for liquidity to create a system match. If we did not have tuning options, I would need to hold back on resolution and impart a signature to the sound of our products to work with the broadest cross-section of systems.

That makes sense to me. Thanks.

I found through experimentation that I like gear that has very low distortion (Mola Mola and Grimm Audio). That may be because my speakers (chosen before the gear) require that in order to sound musical. I followed my ears, not the specs, but the measurements are very good indeed.

Time slowed down for me when I looked at that picture :D

And your daughter likes vinyl too ! Cool ! ;)
