The Elite-series amplifiers are direct descendants of the legendary MS/MPS series designs that put PG in a class of its own… These Elite amps are considered the PINNACLE OF EXCELLENCE featuring only the finest audio components such as Burr Brown op-amps, monolithic signal capacitors, and dual-package . Sanken output transistors. This result is unparalleled sonic performance in a mobile audio amplifier. The sheer breadth of the Elite amplifiers’ dynamic range conveys a musical realism that transcends standard amplifier designs having a +/- 1dB frequency response from 10-50kHz. With seemingly unlimited frequency response and smashing dynamic range the end result is the finest sounding amplifier Phoenix Gold has ever built, period. Oh yeah, they are also built like a brick house and drive low impedance loads without breaking a sweat or sacrificing sound quality.
