It is a two camp showdown one camp being group 1, who evaluate through solely having used their experiences of End Sound produced and the impression made on them.
The other camp, group 2, who are much lesser in their number than group 1, and are using their understanding of Math to influence their assessment of End Sound having been experienced or not experienced for the supply of a description of what is occurring or expected to occur to an End Sound as a result of the Math.
I am in the camp of group 1, but spend a lot of time close to individuals trusted with what is required for being a in the camp of group 2. No mater where the discussions go when evaluations are going on, I keep my listening as the tool to assess.
I still stand by " Is there such a choice available " , as I have indelible memories of very very satisfying moments around recorded music. Where musical encounters had, as a result of different designs for Amp's being resident in an audio system or being demo'd as an added experience of using an audio system are for the time of exposure inseparable for the good impressions being made.
