About the MPX3
The Single Power MPX3 is a single-ended triode headphone amplifier designed with no output transformers on each channel, delivering silky highs, smooth mid-range, and rich bass directly to headphones. It uses Philips 5687 tubes in the output stage and is known for its highly regulated power supply, Gold-Point stepped attenuator with 24 stops, Jensen interstage coupling capacitors, and OFC shielded wiring with point-to-point internal connections. The chassis is stainless steel, and the amplifier is sensitive to power cords, which can affect sound quality. It is praised for its seductive sound typical of single-ended triode designs and is considered a bare-bones yet high-quality implementation of Single Power's design philosophy.
