01-05-13: RrogTrue enough, Ron. But in this case we are trying to address a single very specific problem. And IMO a problem that WILL occur with many classical orchestral recordings no matter how good the system is, as a consequence of excessive multi-miking and processing. And IMO a problem that will NOT occur with a well engineered, minimally miked, minimally processed recording unless there is a specific problem or problems in the system.
The problem with a reference recording is it can sound completely different on every system it's played on. Does that make one system bad and another good? I don't think so. Every system I have assembled gets the most from a separate group of recordings. I think it takes many many recordings to analyze a system. It would be nice if we could use one recording, but it's not that simple.
As Frogman said earlier, it is entirely possible that part of the problem is in the recordings, and something in the system is making it worse. Listening to a known good reference recording would help to isolate the degree to which the system and the recordings may be contributing to the problem. It would also minimize the likelihood that the system will be end up being changed in a manner that compensates for the problems in the mediocre recordings, but degrades or limits its performance with high quality recordings.
It is, of course, a traditional audiophile dilemma that improving the quality of the reproduction of good recordings may in some ways make run of the mill recordings sound worse. And each listener needs to optimize that tradeoff in accordance with his or her own preferences. But it would seem likely to be an exercise in futility to try to optimize that tradeoff without including one or more recordings that are of impeccable quality, and that can be counted on to not contribute to the problem that is being addressed.
