I found it was not that easy to point to a a truly "best sound of the show" this year. To be honest, there were few memorable "best sounds", whereas there were far more "worst sounds". However, unquestionably, one of the most extraordinary demos was the Sanders electrostatic speaker system. I'll tell you this, it may be a "one seat" system, but it has to be the hands down hi-end bargain of the century. 13K buys it all- and that includes speakers, crossover, the incredibly well-reviewed Magtech 500w amp (REG in TAS loves this thing), preamp and cables. It may even include a bow for all I know. As far as speaker cables, I swear Roger must have gone to Radio Shack and asked for something inexpensive to use. When they showed him 18-2 lamp cord, he must have said, "got anything thinner?". I'm telling you, if I didn't hear it I would never have believed it. He played some powerful drum material that knocked me on my ass, in addition to the usual sonic bon bons we typically hear at shows. Extraordinary resolution, transparency, and most importantly, musicality. All at price that can't be touched by anything else, anywhere at anytime. A total and complete mindfk.
I'm very happy to see increasingly positive buzz about Sanders Sound Systems. I did not attend RMAF this year but was floored when I heard it in 2010. So much so that I visited his room every day at Newport this year and even attended the after hours listening sessions, where they did have a CD player to "take requests." The whole system, if you get the preamp with built in phonostage and another Magtech, is $22k. Also, Roger makes his own cables sourced from Belden. When I have a dedicated room that can accommodate it, and the money to spend on audio gear, Roger's system will be my first thought.
Taking into account the price for performance offered, it'd be easy to justify getting a second pair of speakers with a wider sweet spot for when I have guests, and enjoy the Sanders 10C for solo listening.
