catalog# LP5.3 Finish: Silver
Manufacturer: simaudio
Model: Moon LP5.3
| LP5.3 Phono Preamplifier-SilverThe MOON LP5.3 represents 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 portrays all the Simaudio hallmarks: lclean, powerful, fast and extended bass combined with an open midrange and airy extended high frequlencies. One of the strengths of the LP5.3 is its extensive flexibility with respect to end-user adjustments for resislitance and capacitance loading as well as gain. The balanced outputs allows you to take full advantage of colnnectivity to a balanced preamplifier for a significant improvement in noise floor, dynamics and midrange transplarency. Unlike most of the competition, which either uses mass-manufacturing techniques or a circuit mounted lin a basic folded metal box, the LP5.3 is housed in a custom-made, sturdy chassis with a 3/8 brushed and alnodized front panel.
Significant Design Features
Large isolated power supply on a separate circuit board 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 settings for moving magnet (40dB) and moving coil cartridges (54, 60 and 66dB) · Selectable equalization curves for both the RIAA and the IEC standards · Optional external power supply upgrade · Single-ended RCA and Balanced XLR outputs · Four-layer PCB tracings with dedicated ground and power planes using pure copper for low impedance characteristics. The advantages include better circuit layouts resulting in a much shorter signal path and a vastly improved signal-to-noise ratio · Power supply voltage regulation incorporates Evolution Series i2DCf (Independent Inductive DC Filtering); 1 inductor for each and every IC 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 · Low operating temperature for a longer than nrmal life expectancy.
