Ultralinear and Triode. What's the difference

This'll be a bit of a generalization, but here's my impressions based upon experience; Ultra-linear will yield more power and punch, at the expense of holography. Triode will sacrifice the power for a greater sense of dimension, space and textural nuance. Ultra linear leaves me with the impression of sitting much further back in the performance, while triode brings me in closer and gives me a better sense of where the instruments are on stage. If my tastes were in hard driving music like Rock, I might like the muscle and drive of the Ultra-linear. My preferences tend towards acoustic, vocals, folk, blues..more subtle, sparse arrangements in general, with more detail and nuance than most driving rock. I've found for my tastes I prefer Triode. When I had an amp that gave me the option to switch, I almost always ended up listening on triode. No experience with the amps you are considering.

Hope that helps.

Thank you, that was very helpful.

I believe most with golden ears and even the audio writers that critique equipment for a living will tell you triode is where the real music happens.

Gnugear ; as stated earlier , it depends on what type of sound that you desire . Personaly I prefered ultralinear for my rock and blues music . It just has more oomph ! (How is that for an audio term ?)

It is corerct that the two amps , Prima Luna and Cayin , are manufactured by the same company .
But that is where the similarity stops !
It is my understanding that Prima Luna dictates the parts that are to be used where as Cayin farms it out to the lowest bidder . Also , there is supposed to be a quality control rep , from the Prima Luna company , overseeing the production process .
Sales hype or not ? I don't know . However having owned both , the Prima Luna Prologue 2 and the Cayin A 88-T , they do sound quite different from each other !
