About the PA555

It offers four selectable stereo inputs (3x RCA rear, 1x 3.5mm front) and stereo RCA outputs, ideal for enhancing line-level sources like DACs, CD players, or devices with built-in phono preamps. Hand-assembled in the USA, it provides rich, warm tube tone, excellent clarity, and a wide soundstage, making it a versatile and affordable addition to any HiFi system. Includes 15VDC power supply and 1-year warranty.
