I appreciate the human interest side of your report on the Koetsu room at RMAF, but any report on this room would be lacking if it did not mention the Koetsu Coralstone that was set up on a DaVinci arm on the Montegiro Lusso turntable. A second SME V arm on that same table sported the venerable and widely-lauded Koetsu Onyx Platinum ($8,500). In A-B comparisons (made easy by the Aesthetix Rhea phono pre with switchable inputs at the push of a button) the Coralstone TROUNCED the Onyx. It's detail, transparency, dynamics, and accuracy took you deeper into the music than you could have imagined. This despite a pretty poorly set up room, with no acoustic treatments. The only downside is the Coralstone will set you back $14,000. But to have heard it is to carry a musical memory that will last a lifetime.
