Moon by SimAudio LP5.3 RS Phono Pre-Amplifier - Black

The MOON LP5.3 represented a significant step forward in phono preamplifier design. Particular attention has been paid to noise levels and dynamic range, making the LP5.3 one of the quietest phono preamplifiers ever, on par and even superior to many models at significantly higher price points. Sonically, it portrayed all the SimAudio hallmarks: clean, powerful, fast and extended bass combined with an open midrange and airy extended high frequencies. One of the strengths of the MOON LP5.3 was its extensive flexibility with respect to end-user adjustments for resistance and capacitance loading as well as gain. The balanced outputs allowed you to take full advantage of connectivity to a balanced preamplifier for a significant improvement in noise floor, dynamics and midrange transparency. The LP5.3 was housed in a custom-made, sturdy chassis with a 3/8” brushed and anodized front panel.
