All, this is a fascinating discussion and most helpful to me.
I am beginning the process of building my living room system, which will be based on the Coincident dynamo and utilize Coincident Triumph Extreme II speakers. The room has a very lively acoustic, perhaps excessively so for the TEIIs.. I have promised my wife to respect her aesthetic preferences, which means the existing built in book cases will be used to house the electronics and also means the speaker wires will run into the crawl space and back up. This will require fairly long lengths. I got started on this too late to pick up a sufficient amount of 16 gauge stranded, but was able to obtain a 95 ft spool of the 14 gauge equivalent. Rob suggested the 14 g may in fact be preferred for long runs. If, in fact, Mitch's take on subdued high frequency response proves true in my case, that may actually be a good thing for me. I haven't ordered the Belden yet, and I may wait until after I get the speaker wires run and burned in to do so. If I find the presentation still to be a bit on the bright side, it may be that the belden will be just the ticket.
If I caught Volleyguy's point, this is not the first time I have seen an extended period of human effort intended to optimize something go badly adrift. What if, after years and years of research, the market has produced a group of products that are not up to the standards set by a bunch of low tech slide rule carrying cave men who are even older than me? Why can we still not, with all our smarts and technology, make vacuum tubes like they made 60 years ago? How did the entire industry plunge headlong into solid state gear? Anybody here think that the early solid state stuff sounded better than the old McIntosh and Marantz tube gear that was deemed outdated old school trash? Are there any of you who haven't spent time in a brick and mortar salon listening to uber expensive and highly reviewed stuff that didn't sound very good?
Yazaki-San, Jeff Day and Rob have forced us to do something harder than thinking outside of the box. They have forced us to think inside a box that has been buried in the attic for 50 years. Kudos!
