SET vs OTL


Could someone tell me the difference between a single-ended triode amp and an output transformerless amp?

Is it true that despite its operational inconveniences, a good OTL (eg Tenor Audio) will always sound more "natural" than a good SET (eg a Cary 300SE)?

Thanks

Larryi, I should have mentioned that I agree with you that even with the flaws of the AN-e's they are just so musical and emotionally involving that I cant imagine selling them, ever. I've had them for four years and even when I hear systems or speakers that sound better than what I have, I am almost never tempted to upgrade. The 300b is a warm tube but its got some power and in my room and system some slam and good extension in the low and high frequencies.
I would say that a well designed SET 2A3/300B  has the warm sound than also well designed an OTL having the same output wattage.
The one thing that I might add is that 300b tubes can sound very different depending on design and manufacturer. Some 300b tubes sound much more linear than others. Conversely, my experience with different 2a3  tubes (while admitedly more limited than my experience with many different 300b) suggests that they are more alike than different.
It's hard to argue in words and win the war,what we need is to A-B these things  side by side and I hope somebody will initiate  a fest for audio fanatics  into reality.
