Thoughts on Neutralaudio X-Drei, wrt BSG QOL

Blumlein laid out a lot of the fundamentals of stereo recording decades ago. He seems pretty spot-on; the closer one adheres to the basic principles, it seems, the better the sound.

I guess I still have to be convinced about the QOL.

With regards to the X-DREI, some equipment will benefit and others will not. I suspect this will have a more dramatic effect on solid state amplifiers, as RF switching is a bane of such amps, and something that could limit that might be really helpful if the amp has that sort of bandwidth to begin with. Tubes don't have switching issues so I suspect the X-DREI will have less effect on them, but its just a guess, the proof would be to give it a listen.

I guess that I'm commenting on the lack of user comments on A'gon. The X-DREI has had same overall limited coverage as the QOL (1 review each, minimal advertising), both promise substantial improvements over regular signal, but QOL ends up getting momentum of interest and X-DREI...nothing.
Surely all the QOL proponents should also give this unit some consideration. Note, I am not affiliated in any way with product, just getting my head around whether X-DREI or QOL, or indeed neither is way to go.
Will trial device in Summer myself.

Qol is advertising; is x-drei?

Just my opinion of course but I really feel like the less processing you can do, the better. To that end, audio equipment should be RF resistant and phase coherent.

BSG has done a stellar job in marketing the QOL. They took a process that should have zero audiophile appeal and fashioned it in such a manner that it is now the hot audiophile product. Imagine if they had offered the QOL as a mid/side stereo width control? Instead they pitched it as a "signal completion" device and talked about recovering hidden phase information. This obscures what the device really does, but it sounds pseudo-plausible and at least it's readily repeatable. BSG is also smart enough to realize that for some audiophiles it's preferable, it might even be mandatory, for the operating principles of a product to not be understandable, or at least operate under some unknown, newly discovered process. It's the antithesis of the if it measures good... school. Then there's the review in TAS. A feature review by the magazine's editor for a new company with a single product is quite a coup.

BSG should be applauded for bringing to audiophiles the benefits of mid/side processing.
