Purity Each song was captured with a new technology called "IsoMike" (www.isomike.com)...also, all other equipment was insanely fine tuned. You get music that is free from emotion-robbing processes, such as mixing, limiting, compression and artificial sonic additives. These direct recordings utilize DSD (Direct Stream Digital), when you play the SA-CD layer of this disc you will have many times the resolution of standard CDs. The result is sound more detailed, spacious and pure. If this was photography, the improvement is akin to having a digital camera with 8 times the pixel count.
