On the music front, I liken it to a subwoofer’s effect on bringing in the whole spectrum of music to create overall better balance. Given the SR is a very, very low sub frequency, I would think it would be a similar thing, balancing out subsonics to ultimately bring the system to an even finer level of balance. Just a concept.Interestings remark...
Adding subs not only add bass frequencies but also cause probably some "dither" effect......
It is this effect which is at the root of the effect of the S.G. not a special "placebo" effect mainly or a magical transformation of the hearing quality....
I compared the different noise floors of all the devices and gear in the house connected together producing a general noise floor to an ice that hide details of information under his noisy cold envelope.... The S.G. work breaking this ice, then decreasing the general noise floor and making each piece of gear to better communicate his information, letting more details emerge to the listener...
This citation i repeat here give an idea about this "dither" concept:
…[O]ne of the earliest [applications] of dither came in World War II. Airplane bombers used mechanical computers to perform navigation and bomb trajectory calculations. Curiously, these computers (boxes filled with hundreds of gears and cogs) performed more accurately when flying on board the aircraft, and less well on ground. Engineers realized that the vibration from the aircraft reduced the error from sticky moving parts. Instead of moving in short jerks, they moved more continuously. Small vibrating motors were built into the computers, and their vibration was called dither from the Middle English verb "didderen," meaning "to tremble." Today, when you tap a mechanical meter to increase its accuracy, you are applying dither, and modern dictionaries define dither as a highly nervous, confused, or agitated state. In minute quantities, dither successfully makes a digitization system a little more analog in the good sense of the word.
