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 only thing i can input from personal experience is No SET has come as close to the Speed, Dynamics of an OTL.

Owning both i like both SET and OTL and sort of kinda prefer the OTL on every genre of music. Hip Hop, RnB, Dance, Trance, Drum And Bass, Techno, Rock, Movie Scores, Demanding Classical Acoustical or Opera Music I still feel OTL Wins hands down to faithfully reproduce this sort of music.

Whilst it sounds very good on SET amps with more Lush, you can still easily tell the tempo is not exactly the same. Details are lost, slight muddiness to the music playback, this feels like a veil on the speaker, small soundstage than my OTL amps, Slower in pace, the bass is not as articulate or lower in registers. All this is only evident when you do a direct comparison to an OTL.

SET Can sound glorious and Lush/Sweet. it does so with more compromise to details, Resolution. Bass depth and speed. 

Live music is not Warm or Lush or Sweet, since in a Venue or opera house or in a Jazz Club, Its not ever Sounding Lush, Sweet or slow. These are all artificial sweetness added by different SET Circuits.

The biggest problem i find with OTL is that their real magic only takes place when a 16ohms speaker is used. Whilst 8 ohms its still far better them most SET, the real magick only happens on 16ohms or higher.
I own both SET and OTL, but most of the time i kinda just use the OTL Amps more often than SET Amps.
Sorry Charles you probably have more experience then i do but  being an audiophile for over 25 years and the budget to spend as much as i like on this hobby.

Years of buying and selling has tought me many lessons, i would say an evolution in trainning the ears.

I have owned Solid States and SET Amplifiers, Horns and Full Range Speakers, bookshelf and studio speakers to active speakers from studio and audiophile markets, your conventional speakers to even PA Speakers like Danley Sound-labs too. DIY builds on Speakers and Amplifiers from different designs some well known and others not so much.

So far to my Ears with my current experience OTL are superior over any SET Amplifiers in almost any way and so far over any Solid State Amplifiers too.

If you want super lush sounding or slightly colored music then SET would be your weapon of choice but that is more to do with preference and their are many wonderful Sounding SET Amplifiers i personally still would never Sell i like the SET sound too but over each other you obvious know which i would pick. That being said in my main Room for musical playback OTL will always be a permanent keeper. So to my ears and my experience and my preference and conclusion. 

OTL Is Superior Amplifier ( I dont intend to tick anyone off)   This is based on my life journey as a Audiophile.

I currently use the Classic Audio T1.5 and T1,3 Both Field Coils In my home in diffrent rooms both are 16 ohms

I also own Western Electric Field Coil Speakers which is a clone made by Line Magnetic these are also 16ohms

I have the Cube Audio nenuphar Speakers Mated with SET Amplifiers in my bedroom.

I have other rooms with Active Studio Speakers with Tube Pre-amps. Various rooms have different setups.

Overall the combination of Classic Audio Field Coils with OTL is by far the most superior of all my audio systems and i would extend this to saying i have never wanted to change this combo even when i have visited various shows with uber priced audio gears.
