Yes, I'm getting that.
I realized this thread has been about two topics for a while (maybe from page one!). The points about dbt's,perceptual research,placebo effect and such have been an intro to the debate between objectivists and subjectivists and so has been useful for me.
I feel for the next person who, like me, finds this archived thread while searching for info on the Shanling amp b/c as a source for that info, it has been quite diluted. (and I'll own my part in that).
