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

The Merlin needs a little more power than most SETs can produce, if you really want to hear what the speaker or the SET is capable of. With that speaker, hands down an OTL will do better.
Atma,

I used to use the Cary 300B monos with the original VSM SE in a loft (2 parallel walls & 2 open sides terminated only by railings) that was app. 20' across and app. 12' from open railing (speakers) to open railing (listener). SPL capability was completely adequate for my needs and dynamics were just damn stunning.

I also used these speakers with an early production S-30. The combo worked well, but I preferred the 300B by a fair margin. The speakers sounded warmer with the Cary monos and -For My Taste- that delta easily trumped whatever benefits accrued to the S-30. I'm not suggesting that everyone would share my preference.

BTW, I auditioned the speakers with the S-30 and bought both speakers & amp, so you know that I really liked the combo a lot. It's just that, on direct comparison in my home, I preferred the Cary amps for these speakers. I also understand that later runs of the S-30 were pretty different sounding, so my opinion must also be qualified by that fact.

PS The speakers have since been modified to current spec by Merlin and now seem happier with more power. My space has also changed, so an "apples to apples" comparison isn't possible, but the modified VSMs sound warmer than pre-mod. Therefore, they don't benefit as much from the Cary's tonal signature and I've generally paired 'em with PP amps from Prima Luna using either KT66s or EL34s. In fact, I sometimes pair them with SS amps. At some point, I'll probably revisit your OTLs again since I find playing with these combos endlessly fascinating.
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;)
It's undeniable that every triode has its' own characteristics. A reputable manufacturer and/or experienced hobbyist knows this. Simply reviewing the electrical properties of each tube is sufficient proof.

Given a speaker is capable of being properly driven by a variety of SET amplifiers, the sonic signature of each triode is is clearly demonstrable.

To deny that is disingenuous.
Thanks Atmasphere for clearing up the issue of safety/reliability of direct coupled. A friend has direct coupled OTLs hooked up to Sonus Faber Stradivari speakers. When asked about what might happen if a tube shorted, he just shrugged his shoulder and said: "I guess you just buy another speaker."

On the which-low-powered-triode-is-my-favorite debate, I like 45s, they are sort of in between: not as dry and lean as the 2a3, not as warm, and lumpish as the 300B. 45s have a big low end, but that low end is also tight. The other nice thing is that a lot of decent older 45s can be had without spending crazy dollars. The PX25 is a nice tube too. I am not a big fan of 300Bs, but some amps using them can be quite nice, particularly when equipped with Kron 300Bs.
