The MOON PSX5.3 dedicated external power supply for the MOON LP5.3 Phono preamplifier elevated this award winning phono stage to an extraordinary level of performance far beyond the competition and unmatched at this price. Reference level analog LP playback became even more affordable. The PSX5.3, was housed in a chassis identical to the LP5.3, featured a special "pi-type" filter and a dual voltage regulation system that reduced the LP5.3's already very low noise level on the DC signal by a mind-numbing 150dB.
Some of the benefits that the PSX5.3 brought to the LP5.3's already astonishing sonics were an even better signal-to-noise ratio that left you with the impression of increased gain; more realistic rhythm and pace; more natural life-like high-frequencies, allowing you to better differentiate between various cymbals in a recording; and a deeper blacker background.
