What class of amplifier has the most high definition sound ?

Though I haven't yet heard one (soon to be rectified), I am curious if the answer turns out to be a direct-drive tube amp driving an ESL loudspeaker. No amp output transformer, no ESL step-up transformer---sounds very promising, right? An OTL driving an ESL gets half the way there, but that designs (generally) somewhat high output impedance brings its own potential penalty.

"High definition" is very much dependent on design.  Except for the hopeless designs of Class D.  Nothing can bail out a design that is so fundamentally flawed.

I can't believe no one got that.......

Didn't you hear the groans, Ozzy?

I would say OTL class A

Ditto that.
But there aren’t any speakers "THAT I LIKE" yet without any colorations that they can drive with ease (without bandaid fix autoformers), top to bottom, so "TO ME" your ****** if you do and ****** if you don’t.

The only way is to make a hidiousely big OTL Class-A with a bazillion tubes, so they could drive hard to drive speakers speakers that are designed to be flat, low coloration, low distortion and without horns to make them efficient.
