CH Precision P1 phono stage NEW

It is well known that the electrical characteristics of turntable cartridges differ greatly from one cartridge to another. Ohm’s law shows that Moving Magnet cartridges will generate larger voltages, while Moving Coil cartridges are generally more efficient at delivering current. Phono preamplifiers should take full advantage of the cartridges’ strengths and amplify the signal in the way they work best. With two dedicated MC current inputs and one MM/MC voltage input, the P1 provides the optimal coupling to all types of cartridges. In addition, fully symmetrical, discrete class A stages as well as the highest grade, tight tolerance components allow the P1 to deliver the high performances for a transparent yet natural sound.
