I would like to make some clarifications to avoid that some messages are misinterpreted due to lack of contextualization, insinuations of others, or simply my bad wording in English (I also edited for appropriate clarity).
There is apparently unanimous recognition of the fact that XTCs in general can provide an objective and subjective result, depending on the fidelity paradigm adopted.
As far as BACCH is concerned, it is clearly based on a effective and ingenious mathematical model, which has in turn been confirmed with extensive scientific tests by research institute. No one doubt about this. Nor that it provides a more 3D perception than the system without it.
What we consumers lack apparently (but if this is not the case the forum should serve to help us in this sense) and which therefore makes it impossible for us to generalize, draw unambiguous conclusions and make bold or presumptuous statements (what makes me react), are the objective data that show in the practice, on a representative number of real cases, how effective/dependent the objective result is, and how statistically preferable the subjective one is (so my aforementioned comment).
Surely the R&D tests have been conducted and we could surely make the assumption that they are reasonably good given the seriousness and the validity of the technical information shared, nothing wrong. Some comments here also seem to confirm this.
But ASR is the place where objective elements/criteria of judgment are sought, precisely to dispel the uncertainty/relativity of subjectivity, which we know how distorting the world of consumer audio.
Discussing a product so evidently the result of scientific research, without scientific data, only create confusion.
Obviously we cannot hope or expect that there will always be a third party that does this work for free (like ASR) nor that the developers of the technology can show all the results of every kind of test related to real world scenarios.
So the most reasonable thing to do, in my opinion, is to make consideration related to the theory and the practical world, as I tried to do, but where, however, there will be no consensus regarding what it is. And in any case it makes no sense to oust niches in fact, I admit.
So the only thing that remains is to recognize the fact we are all rotating around a spherical matter and that every subjective opinion or fact that we report in this discussion, if not extremely well contextualized, will serve no purpose other than to increase entropy and therefore to deform the sphere, in favor of contrasts and polarizations and apparently biased messages.
In a science forum we should effectively try to be objective and balanced, as far as possible for people in flesh and blood (and emotions). It's for interest of all. Unfortunately not always easy, especially when someone else starts not being. As far I'm concerned I'm sorry for this.
I hope it is a discourse that can be shared by everyone.
That said, I invite all the enthusiasts to look for the personally most reasonable path to reach the own goal of enjoyment, that is the ultimate essence of audio world. Soon I hope to try XTC on my system too.
