Octave V 40 SE | The All-rounder
The V 40 SE is a line level integrated amplifier with 2 x 40 W peak output power. He is a further development and direct descendant of the successful V 40 and V 50 amplifier models. His powerful, clear bass fundamentals and his captivating resolution in the high frequencies win much respect. His unique features lift the V 40 SE into the 21st Century, while his performance earned him the rare “Stereoplay Highlight” (issue 07-2009), a prestigious award bestowed by the German high-end audio magazine Stereoplay.
The V 40 SE output stage consists of two power pentodes (Type 6550) for each channel. Due to the BIAS Control and Monitoring System, the use of other pin-compatible output tubes is possible to match the amplifier to personal taste, or to benefit from new or improved tubes.
Like all OCTAVE Amps the, V 40 SE is based on the enhanced pentode configuration. This configuration ensures the absolute stability of the amplifier against the unstable impedance of the loudspeaker. Impedance mismatch is without consequence, and the V 40 SE is stable down to a 2 Ohm Load. An important contributor to this stability is the single impedance output transformer.
The V 40 SE is the perfect amp for speakers with an average efficiency rating.But not only is the low impedance capability an advantage, with his exceptional Signal-to-Noise ratio of –110dB / Full Power he is also an ideal partner for high efficiency loudspeakers.
