SET sound refers to the sound characteristics of a SET tube amp and not the sound a "set" of musicians make in a studio.
My experience is limited compared to others here but what I did hear with a SET tube amp with Audeze headphones finally clued me in to what all the ado was with that SET sound. I never found it quite so fetching in a standard system: amp, source and speakers (lack of exposure) and discovered just how scary good it can be with a headphone set up.
The performers will have that "in the room" quality and appear to be "lit up from within", including the very air that surrounds them at the time of the recording. With all of this comes subtlety, shadings, tone and other qualities that make it a convincing recreation. Admittedly, there are inherent limits in what SET can do as they are very low powered amps that can easily clip and require very efficient speakers. The highs tend to be soft and though the bass is there, it's not as taut and deep as other designs. But what it does with that midrange is magic.
For the experts out there, please don't take me to task as this is what I understand it to be. My comparison of the Marantz to a SET setup was in reference to that magical midrange that it recreates and the ability to present something as "lit up from within".
You'll get a lot of debate about this and even better and more thorough explanations but that is what I've taken away from it.
All the best,
