no longer for sale

Superb solid state headphone amplifier that does it all, running all headphones gorgeously whether balanced (dual XLR) or standard single-ended (1/4"/6.35mm plug). Has both balanced and single-ended inputs, and can be run from your balanced or single-ended source/CDP/DAC. Gives you balanced output from single-ended sources, single-ended output from balanced sources, etc., fitting easily in to any system. Famous for its tube-like "you are there" presence and purity and tone, coupled with the awesome power to really drive and create huge dynamics from the blackest of backgrounds. In short, delivers all the audiophile chill bumps while still being fun to listen to and tap your feet! Unit circa 2009, 9/10 condition but for a few light marks on Hic Sunt Leones badge. Unit was $4300 USD new. I will ship worldwide (some exceptions). Buyer pays shipping. Accept Paypal and major credit cards via Paypal. RP010BMkII is the evolution of the classic and successful RP010. In order to make the RP010B a real the top performer both in Single Ended traditional headphone output and Balanced Headphone output a “Quad Mono” topology has been adopted, this mean four amplification units and two dual power supply, When used in single ended ( traditional headphone) it is a dual mono amplification unit, when used in balanced output connection four amplification unit are working, two for each channel. RP010B amplify separately the positive and negative phase of the signal for each channel. This is a real no-compromise solution. Very interesting is the possibility to drive balanced headphone from unbalanced source, in this configuration the amplifier convert the unbalanced input signal to balanced trough an extraordinary hi-quality internal splitter unit, made on discrete components base. RP010-B "Something very different !" The RP010B is built in heavy box using copper and solid avio machined aluminium, the components are from best quality production, and the construction is at mil quality. The two power transformers ( made under our design ) are soaked in a special vinyl resin and shielded in order to avoid vibrations and erratic magnetic fields. The power supplies are a combination of Capacitance Multiplier and RC cells, they assure a clean and redundant current to the amplification electronics. The input gain amplification stage is made by a discrete FET differential amplifier controlled by a constant current generator.. The darlington bipolar power transistors are controlled by an active constant current generator, The accurate internal construction based on shielded non-magnetic metal boxes jointed with the highly accurate component selection and the precise design, make possible a reliable and silent amplification without using any any negative feedback circuitry, either local or global, The benefits on sound are really remarkable it terms of transparency and deepness feeling. The astonishing linearity from 2Hz to 100Khz (-0.2 db) and the impressive figure of 128 dB of dynamic range, jointed with the advantage in terms of soundstage and transparency done by double dual mono architecture and the total zero negative feedback solution, make the RP010-B a trough unbeatable top performer offering great musicality, transparence, and dynamics.(Available in Silver or Black Faceplate Option) The RP010-B can accept balanced and unbalanced input. and can work in any combination. Balanced input to Balanced Output ( Full Balanced Mode) Unbalanced input to Balanced output ( trough the internal highest quality phase splitter) Balanced Input to Single Ended Output Unbalanced Input to Unbalanced Output Rear paner offers: Balanced XLR Input Balanced XLR Output( a by-pass from input) Single Ended (Unbalanced) RCA input Single Ended (Unbalanced) RCA by-pass output SPECIFICATIONS Maximum Output: 1500 mW **** ( with selectable limiter at 500mW) Inputs: 1 - line balanced or Unbalanced Bandwidth: 2Hz-100 KHz within 0.2db Gain: 6-25 db adjustable factory preset typical 12dB THD: 95db Amplification Class: Always A-Class Channel L-R Balance ( pot at 50%): 0.02 db Dimensions cm: 45x30x12 Noise Floor: -116dB ( IEEE 20Khz band preset) Weight (Kg): 14 kg.
