Graham said: The Octave Audio V 40 SE is more than a bit special. It combines the grip and drive of a much more powerful amplifier with levels of transparency and detail that you’d be happy to find in a far more expensive product. It appeals to both the heart and head, and delivers a sound that modernizes traditional notions of what a tube amplifier at this price point can be and do.
