E-Stat, you seem to have difficulty with the idea that two people can be knowledgeable about a subject and have different opinions. You also have an inclination to quote quite selectively.

1. You arbitrarily consigned my experience to only the "sound reinforcement" venue. Your presumption is limited and incorrect. You continued your incorrect assumptions even after it was pointed out. Most people would have at least given a nod to the error of their presumption. Your choice seem to be to continue the bluster. It also seem you have never been in a recording studio.

My reference for live performances is no system at all.
2. Then that leaves you with a lot of wonderful performers you would have never seen live. Very few jazz singers perform live without amplification, even in small clubs: Sarah Vaughan, Ella Fitzgerald, Ray Charles, Joni Mitchell and all of their more recent counterparts such as Karrin Allyson, Marlena Shaw, Janice Hagan, Christine Rosholt, Cassandra Wilson and so on, In fact, it was the invention of the microphone and PA system that allowed a whole new style of singing that departed from the operatic and vaudeville style. Had the world followed your puritan lead, the development of a whole range of music would have never occurred.

Yes, for certain types of music, on certain types of instruments in the proper sized hall, no amplification is preferred. However, that leaves a lot of live music on the cutting room floor that perhaps you are willing to abandon, but I'm not.

I guess your statement concerning "references" was an effort to demonstrate your audiophile pedigree for all to see. Well, congratulations. The podium is all yours. I've got some backup maintenance on my music collection to do this evening. See you around.
