An important note. The systems listed here are by no means the only way to audio nirvana but they are systems that we have found to stand the test of time, reliability, usefulness and sonic greatness. We present them for that purpose. These are actual real world systems, not virtual experiments. Every one of these systems is in use by one or more of our customers. Most of these systems are made up with components of particular merit creating a sum even greater than the parts.
