Willsenton R-800i 805 Dual 300B Class A Tubes Hifi Audio XLR Balanced 50W Power

The Willsenton R800i 805 is a serious high-power single-ended Class A tube integrated amplifier, using 805 output tubes driven by 300B tubes to deliver around 50W per channel. This combination gives it an interesting balance of SET-style harmonic richness with substantially greater power and dynamic authority than conventional low-powered 300B amplifiers. Its point-to-point construction, large EI output transformers, separate power-supply arrangements and adjustable bias further reinforce its traditional high-end valve design philosophy.

Sonically, the R800i 805 is characterised by a rich, dimensional and highly engaging presentation, with excellent vocal texture, natural instrumental timbre and a spacious soundstage. The 300B driver stage contributes beautiful midrange fluidity and harmonic expression, while the 805 output stage provides stronger bass control, dynamics and scale. It is particularly attractive for vocals, jazz, acoustic music and classical recordings where tone, imaging and musical realism are important.

One of its biggest strengths is its ability to combine the emotional character of SET amplification with 50W of Class A power, allowing it to work with a much wider range of speakers than many traditional SET designs. With 4Ω, 8Ω and 16Ω outputs, XLR input, ALPS volume control, remote control and external bias monitoring, it also offers considerable flexibility. Overall, the R800i 805 is an amplifier for listeners who want tube warmth, 3D imaging, natural timbre and musicality without sacrificing power, scale and dynamic impact.
