The Mountain Bluebird ZPS preamplifier is a two box version of the Bluebird ZPS preamplifier. Housing the power supply in a different enclosure than the amplifier section of the Bluebird, results in a significant reduction of power supply noise (60 Hz in the USA). This noise is due to electromagnetic coupling of the rectifier switching noise and the power transformer stray fields as well as mechanical coupling of transformer hum to the amplifier section via the preamplifier’s enclosure. In addition the separate power supply permits increasing the power supply’s capacitance by approximately 30%. This added capacitance coupled with the reduction of power supply noise allows for a more defined and articulate bass, an improved soundstage and better transient response. The use of Vishay resistors, OFC connectors and our Omega wiring throughout the Mountain Bluebird further improve on the already stellar performance of the Bluebird ZPS. |
