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

Its the amp design,construction as much as the output tube thats responcible for sound quality. Having owned over 10 -45 SET. Probly arround 25 others SET many OTL SS PP etc. I can say that I did not find 45-50 SET to be the best in anyway. I look at total design not just tubes used and make dam sure it matchs loudspeakers or you SET yourself up for falure which is what most 45 2a3 owners do. Wavac, MasterSound, PAD, John Hogan have owned these 300b amps and they sounded much better than my 45 SETs and I have owned most of the great 45 SET amps that get raved about. With SET match your loudspeakers to amp or forget about it. Would say the same about OTL designs.
We all have personal tastes. Bill likes 45-50 as do I but I still stand by my post and Bill still using the mastersound you sold me;)
Never said they dont have a slightly dif sound old Bill but I do disagree that 45 50 SET are the best all have there use and most can be used in hi-performance amp design. Maybe you need to relax a bit. Take some time off enjoy the weather and not fuss so much over others who disagree with you for someone always will.
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.
Said I owned over 35 SET amps 6 of them-45 SET, 4-OTL. Not that I'm 35. Would happily trade to be 35 again. I will leave this thread nothing worth while here. All I do is design hi-eff loudspeakers mostly for small power amps like SET what the heck would I know about driving loudspeakers with small power or OTL.
Never said 300b is the best just that I disagree that 45-50 SETs the best for nothing ever is truly the best. You speak in adsolutes as Masty pointed out. And Bill sure Ive owned far more flee powered SETs than you think over 35 at least want pics? But I will take your sugestion Bill and ignore you. Instead I will listen to my collection of SET amps. On my many hi-eff loudspeaker designs take the day off. Bill sells 300b amps to folks bet he doesnt express his preferance then.
