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

Robert,

I fear you may have misread my sarcastic comment which was nominally directed to Johnk.

Perhaps with a little more experience you will understand....my post.

Bill I have much experience with SET and audio design. Transformers mater as much as tube type not all 300b have weak bass rolled off hi. And as far as 45 50 SET as you say the best. Best for what? at 1.5 watts what can you drive? You need a loudspeaker designed to run off such low power and I have built many. And this low power doesn't drive woofers into low frequencies very well. Most of the loudspeakers I design for 45 SET etc have little bass below 40hz since 45 SET has little drive. If I want bass to 25hz or lower need biamping. So I agree 45 SETs best for biamping;) Its the transformer and amp design that gives extended range not the tube type. Bill with a bit more experience you will learn this. Take care and happy listening.

John,

Glad to provide a laugh.

Your last comment is interesting in that I had posted earlier looking for info on loudspeakers that provide:

A) Appropriate sensitivity and load for a 45 SET amp

and

B) Sufficiently flat and extended bass response to even judge the bass capabilities of these amps (i.e.- no biamping).

Zu's full range passive (Essence?) looks like it might qualify. Any thoughts on this or other candidates would be appreciated. Again, budget and availability are considerations here.
