I don't know whay, but I enjoy a detailed presentation. I lucked into a slew of vintage 6SN7 pairs and I was rolling them in the balanced input sockets of my preamp, and the ones that made the biggest positive impression on me were the ones that brought out the most detail. But that could be just a thing with me.
I always thought of "bright" as kind of a harsh treble. Maybe a treble that is too "sparkly."
To me, "hot" kind of means an up front/in your face presentation, and for some recordings it works well for me. But that's something that a little bit will go too far in a hurry. I wouldn't call my own system "hot," but I certainly own at least a few recordings that I consider to be "hot."
