Hi Chuck,
Great questions, these are the questions we had 4 years ago !
How can digital equipment delivering an un-corrupted data stream, buffered and timed with precision, sound any different ?
A consistent observation is the sound quality is heavily influenced by OS activity and processes, the delivered bits are the same, they are all buffered and timed with precision so what’s going on ?
3 years ago Emile and I invested in acquiring quite a bit of RF detection and spectrum analysis gear from these folks https://www.aaronia.com/products/antennas/
What we can observe is that the RF soup coming from all of the clocks and oscillators gets everywhere and is very difficult to dramatically attenuate. The RF noise is transmitted over the air and piggybacks on every cable, conductor and ground plane. We can also observe that CPU and RAM activity changes the observable RF emissions.
Another interesting and consistent empirical observation is that the listener heard sound quality coming from digital equipment is very vibration sensitive and of a similar order of magnitude to the vibration sensitivity of analog equipment.
I would humbly propose that the sound quality differences we are hearing are being transmitted by RF noise emissions emanating from the myriad clocks and oscillators in digital equipment, and being detected by the analog components and cabling in the playback chain.
All of the hardware and software features which Emile has implemented deliver sonic differences that are easily perceivable and consistent with a mechanism of RF transmission of noise, both SQ enhancing, and SQ degrading. The design strategy is to shape the noise, minimizing the SQ degrading RF noise and to amplify the SQ enhancing RF noise.
Emile scratched the surface with the SGM 2015, developed more with great data points and personal experience from brother Ben resulting in the SGM Evo, and now pushed to another level in the Extreme
