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.
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.
