The name Koetsu has long been held in high regard by audiophiles. Almost mystical attributes have been associated with the name. The Red was one of the early examples of a high-performance audio device that had some obvious shortcomings, but presented music in such an involving and inviting way that the positive aspects of the performance far outweighed the negative ones.

Koetsu continues this tradition today, although their later products tend to move away from the expected family signature sound, minimizing but not eliminating the unique character we associate with the name Koetsu. That sound is apparent, though, as we look at various models in the line, with the more modest offerings offering a more historic or traditional sound.
