RIAA14B

All tube, phono pre-amplifier with low noise, low distortion, accurate RIAA curve and high overload margin. RIAA14B has 2 selectable RCA phono inputs with individually adjustable cartridge loading, 1 RCA phono output och 1 balanced XLR output.

NOTE! all amplifier stages are 100% tube and OTL, no solid state components nor transformers or chokes are used in the audio chain.

Advanced stabilised power supply, (anode och heater) give very low levels of hum and noise.

The amplifier is built on 3 PCBs, the chassis is made of 10mm aluminium which gives extraordinary mechanical stability and completely remove vibration induced noise.

RIAA14B is a perfect fit with PRE14B + PA3, PA12 or PA34 OTL power amplifiers, the high performance of PRE14B + PA3B, PA12B or PA34 make it important to also put high requirements of the RIAA preamplifier to fully utilise the full performance.

RIAA14 fulfils these goals and will not affect the crystal clear sound from our OTL amplifiers. RIAA14B is of course also a perfect choice in any other case where a real transparent RIAA preamplifier is desired.
