Preamplificatore Moon LP5.3 RS

Preamplificatore Phono MM/MC HiEnd, uscite bilanciate, peso 3 kg

The 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: 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 is its extensive flexibility with respect to end-user adjustments for resisitance and capacitance loading as well as gain. The balanced outputs allows you to take full advantage of connectivity to a balanced preamplifier for a significant improvement in noise floor, dynamics and midrange transparency. Unlike most of the competition, which either uses mass-manufacturing techniques or a circuit mounted in a basic folded metal box, the LP5.3 is housed in a custom-made, sturdy chassis with a 3/8” brushed and anodized front panel.

Significant Design Features:
· Large isolated power supply on a separate circuit with 2 stages of voltage regulation
· End-user adjustable impedance loading (10, 100, 470, 1K and 47k©)
· 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 PSX5.3 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 includes Evolution series i2DCf (Independant
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
· Low operating temperature for a longer than normal life expectancy.
