RPX-303 MKII discontinued

The MKII update of the RPX-303, released in 2012 on the same product page: the outside is unchanged — RudiStor kept the very same photos — the difference is inside.

RPX303 MKII differs from the earlier version for using more powerful but smaller transformers, in order to eliminate any possible EMI, and for an oversized power supply capacity — this increases the sound transparency and the dynamics.

RPX-303 MKII is a full balanced quad mono amplifier dedicated to high demanding audiophiles, made by two independent dualmono solid state A-Class amplification units, with double power supply. It has a unique 4-section high quality potentiometer in order to make simple the use and the reaching of the desired volume.

A pure Class A amplifier, working both in balanced or unbalanced mode either in input and output, or in any combination of them. The high current output, the absolute zero negative feedback (local or global) and the great capability of controlling the transducers make it an astonishingly transparent and dynamic amp.

The double dualmono topology ensures the deepest and more natural head-stage. The oversized four section power supply ensures more than needed clean current, the enclosed transformers ensure no EMI roaming around the amplifier, hence no hum or buzz.

RPX 303 MKII operative modes

• Balanced Input to Single Ended Output
• Balanced Input to Balanced Output (full Balanced mode)
• Unbalanced Input to Balanced Output (through an internal phase splitter)
• Unbalanced Input to Unbalanced Output (traditional SE dualmono amplifier)

Headphone outputs

• Balanced left and right
• 2 × 6.4mm jack (unbalanced out)
• All the outputs can be used at same time

Preamplifier output (standard): Balanced Out XLR, Unbalanced Out R-L RCA. The set of output sockets can be configured to be controlled by the volume knob, making it a great preamplifier.
