Know anything about the BSG Technologies QOL?

Let's hear about the solid science. Since you're inviting the world to call or email, save yourself some time and explain it clearly here.

I've had any component or cable inserted line level after the necessary components (source/pre-amp or integrated) which has not absolutely detracted from the pristine nature of the signal, and that includes all power filtering/regeneration devices.

So, this unit is all analogue, is not a processor, and is an add-on to the signal. That means it degrades the signal in terms of absolute clarity. What does it do to merit its insertion into the signal chain?

Typo: second paragraph: "I have not had..."

The responses continue to cause more confusion than help. The CEO says it's the biggest thing since stereo, and the dealer downplays it as perhaps more efficacious for MidFi than HiFi.

The website which I visited prior to asking my question here had nothing helpful regarding the technology; it was fluff, promotion. The discussion here from BSGT related persons is the same. The other thread on Agon regarding QOL mentions phase. Perhaps QOL is an enhanced phase inverter. I wonder if that's why one cannot switch between RCA/XLR inputs and outputs while using QOL? Sorry, but the lack of clarity in responses in my mind begs for answers.

I know one thing; when there's a truly staggering improvement/breakthrough it's efficacious with more certainty as one moves up the audio chain in terms of system quality, not with less certainty. The answer given causes less confidence, not more. :)

Setonaudio, thank you for your cordial responses.
