Haiku-Audio introduces BRIGHT RA ahead of Warsaw show
Haiku-Audio's new BRIGHT RA is a hybrid integrated amplifier joining the BRIGHT family, which has been part of the range since 2012. Its design combines an ECC82 valve preamplifier with a three-stage transistor amplifier circuit.

Haiku-Audio will present its new BRIGHT RA at Audio Video Show Warsaw, running from 23 to 25 October 2026. The hybrid integrated amplifier is rated at 80W into 8Ω and 150W into 4Ω and is priced at PLN 12,900. The presentation will take place in Room 314 of the Radisson Blu Sobieski Hotel.
The preamplifier section uses two ECC82 valves in a single-ended configuration. A three-stage transistor circuit handles amplification for the speakers, with the first two stages using single-ended Class A topology. The amplifier has a bipolar output stage and an actively regulated power supply. Its specified operating class is A/AB, with push-pull operation.
BRIGHT RA provides four pairs of RCA inputs and one pair of speaker outputs. Input sensitivity is specified at 600mV. The published frequency response extends from 14Hz to 100kHz at −1dB and from 8Hz to 250kHz at −3dB.
The amplifier measures 45 × 36 × 14cm and weighs 14kg. Maximum power consumption is specified at 400W.
Haiku-Audio was founded as a family company in Kraków in 2012 and produces valve, hybrid and solid-state amplifiers and preamplifiers. Alongside its hi-fi range, the manufacturer designs and builds custom equipment for recording studios and musicians. That work includes line and microphone preamplifiers, valve-based tone controls and guitar amplifiers.
