RP2 discontinued

The entry-level of the RP series, yet with all the characteristics that distinguish the products of the upper ranges.

At the input, voltage amplification is entrusted to a double triode; the power section, as in all RP models, is Class A with Zero Feedback. Despite the compact dimensions there is no integrated circuitry — all components are top quality, selected and wired point-to-point with silvered wire.

Unlike the other RP models the power supply is external: a classic plug supply provides the necessary voltage, while inside the unit an additional filtering system provides the cleanest possible power to the amplification section.

The RCA connections are gold plated. A rear auxiliary output with RCA connections allows the RP2 to be used as a line preamp or “Valvolizer”.

The tube is mounted externally — given the low supply voltage it represents no danger and the heat developed is very limited, while the external tube gives the unit a very appealing look.

It provides a very detailed and soft sound; excellent for every genre, it is particularly suited to Jazz, Blues and chamber music. It presents no impedance matching problems, adapting to both low and high impedance headphones, though the use of medium-high sensitivity headphones (98dB and up) is recommended.

The RP2 was later followed by the RP3-D — a compact hybrid headphone amplifier with a built-in USB DAC, a pair of Electro-Harmonix 12AU7/ECC82 tubes and an external power supply, sold at around $890.
