Colin said: It’s likely the most sophisticated amplifier available at its price. In this ever-changing world, sophistication and modularity are good things, and the C 390DD offers both. That it’s also a superb music-reproduction device and sounds invisible is a major achievement, and, at its price, a phenomenal one.
