Its exacting circuits and power supply receive special upgrades in order to further allow the fantastic potential of our low memory technology to come to fruition.
The power output remains the same as for the Model ISx, but micro-dynamics and resolution are increased to allow greater expression of the feeling and intention of the music.
Thus also the sound stage is wider, detail is sharper and the presentation is more mature, even if the sound balance remains respectfully neutral as with the Model ISx.
Its extreme transparency, over the full bandwidth is in contrast with midband focused transparency of the best tube amplifiers. Its micro dynamics, never aggressive, clumsy or confused is in contrast with almost all transistor and digital amplifiers.
Never has an amplifier done so much at such an affordable price, for music and for the pleasure of the listener.
