Launched in 2006, Discontinued in 2010

The MOON LP5.3 represented a significant step forward in phono preamplifier design. Particular attention was 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.

Technical aspects


 
Large powser supply on a separate circuit with 2 stages of voltage regulation
End-user adjustable impedance loading (10, 100, 470, 1K and 47K ohms)
End-user adjustable capacitance loading (0,100 and 470pF)
End-user adjustable gain for moving magnet (40dB) & moving coil cartridges (60dB)
End-user adjustable equalization curve (RIAA or IEC)
Optional PSX5.3 external power supply
Single-ended RCA and Balanced XLR outputs
4-Layer printed circuit boards with pure copper tracings for a much shorter signal path; This results in greater sonic accuracy and a dramatically improved signal-to-noise ratio
Power supply voltage regulation includes Evolution series i2DCf (Independent Inductive DC
Filtering); There is one inductor dedicated to each integrated circuit type component (DAC,
Op-Amp, etc.) in the audio circuit’s signal path - 2 stages in all
Extremely short signal path for a faster transient response
Accurate matching of the finest high quality electronic components.
