Has biwire speaker cabling become "old" ?

Yes, Richard has done a great job with that site.  I don't know any others who have such a comprehensive Q&A page like that and Richard himself answers the questions.

Email, I can't wait to hear the you use in your system.  As you know the only thing is using the same length and type for each and every run.  

Thanks to whoever pointed out the faq on Vanderstein's  site.   A great read.  

Bare wire so much better than crimped/welded/soldered joints to plugs/spades.

no romance, how can you make a statement like that?  There is so much that goes into any cable that you can't just make a blanket statement like that as fact.  The real fact is that any bare wire will start to 'gas' over time and that will degrade the sound tremendously at this level.  If you have a strong cold weld like AQ makes along with a top of the line silver dipped spade, your connection is as good as anything else and you won't get the gassing, so it will continue to be a better connection. Other companies have done research on their connections and many are much better over time than bare wire.  Just saying 

Are we done kissing RV's tush?  Ok, let's all use our own brains and try different methods.  I've played the field and have found that Biwiring makes a huge difference if you use a cable that actually is designed for high end performance and not just for connecting electrical appliances together (read wire only).  Hopefully your speakers have the terminals feeding seperate crossovers for the low and high frequencies...otherwise forget it!  MIT has just such cables....enjoy.
