why does triod mode sound better than ultralinear?


I know this has been debated.... I just bought a CJ MV-60. It is factory set for ulta linear. It can be reconfigured for triod but it takes a mod. I'm just wondering why it *should* sound better... I would hate to give up 1/2 the power without understanding why.

Thanks

It is not a question of which is better it is matter of preference. A triode valve has a more linear response than a Pentode valve. This leads to a lower harmonic distortion when the triode is set-up correctly. The ultra linear design is a class A/B amplifier. The configuration of the output valves is set-up to help over come the non-linear response of the valves. It is also worth pointing out it is the harmonic distortion that give a valve amp its "sound". A SS amp has a far lower harmonic distortion figure. The SS introduce mainly odd harmonics because when it is overdriven it clips quickly rather than gradually like a valve amp. A MOSFET amplifier is a good as it gets as far as Hi-Fi is concerned because they are far more linear than any valve however Hi-Fi is not what a valve amps are about.
