Launched in 2007, Discontinued in 2011

The MOON P5.3 Preamplifier follows in the footsteps of the legendary and award-winning P-5. It  employs numerous technologies from our Evolution series. Featuring five line-level inputs, a user-configurable “home-theater ready” input, an IR input for external control and a 12V trigger for convenient operation, the P5.3 Preamplifier offers a level of sonic performance and flexibility that the competition can only hint at. Raising the bar even further, an optional internal phono preamp is available with adjustments for gain level as well as capacitance and resistance loading. 

The SE version features an upgraded volume circuit with a greater range of volume steps (0 to 99) compared to the original version (0 thru 50).  The SE version offers tighter matching and tolerances for certain critical electronic parts.

Technical aspects


 
IR input for external control (all discrete codes)
One line input which bypasses the gain control stage to accomodate a component, such as a
home-theatre processor, whose own volume control is used instead
An extremely short capacitor-free signal path measuring only 10 inches in length from input to
output connectors, eliminating virtually all potential sources of interference and producing a
sonically faster transient response
An oversized power supply with 3 stages of DC voltage regulation
Open loop zero feedback circuit topology using absolutely no capacitors
anywhere in the audio signal path
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 - 14 stages
Accurate matching of the very finest high quality electronic components
A symmetrical circuit design
4-Layer PCB’s with pure copper tracings for a much shorter signal path; This results in
greater sonic accuracy and a dramatically improved signal-to-noise ratio
 Extremely rigid chassis construction to minimize the effects of external vibrations
 Improved reliability through the elimination of moving parts
 Designed to be powered up at all times for optimal performance
 Includes FRM-2 remote control.
