I've been running thru various audio sites/forum boards discussing ongoing tweaks. What I'm finding is they can be divided into 2 camps: those that have a reasonable physical and psycho-acoustical basis, not dressed up in overbold claims, and esp. with reasonable discourse of methodology involved; they also seem to have consistency of positive comments. I would place units like the SpatialComputer Black Hole bass attenuator, and balanced power transformers in this category, with defined measured data stacking up with positive user consensus (and at a reasonable price for good measure).
In the other camp, we have the items that have limited discourse, resort to new age explanations not rooted in the physical world. Of course these units promise more than any other unit, as far as rewriting the whole rulebook on audio reproduction. Additionally, and coincidentally (?) these always seem to be the most expensive. In this camp I would place items such as Shakti Stones/Hallograph, ASI resonators, Lessloss Blackbody, Neutralaudio X-DREI, exotic cables predicated on unsupportable concepts, and my current favourite, and the subject of this thread: BSGT QOL.
Please, let's have a proper discussion on how this unit works, primarily from the manufacturer. Surely a decision to use an item long term has to be based in real world principles, and if the QOL qualifies, let's hear about it. I'm sure fuller discussion of how it achieves it's effects can be made without breaking commercial confidences etc.
I'm convinced that the bold, unquantifiable claims made by these items leads to such a divergence of opinions: some listeners will like the sound, become proponents for it and go with the quantum leap premise. Cooler heads will find variability in it's effects, some good, some not so, as a result move away from it, and then find the obtuse explanations and overbold claims even more queationable.
For me at least the growing consensus between early adopters, some of which have become dealers, and specialist reviews seem to be pulling in different directions, the only consensus being that the unit is v.system and even recording/individual song dependent. This just couldn't add to the sense of ease I need my system to provide me.
Looks like I may have 'put the cat amongst the pigeons'!
