There are plenty of "harsh" amps and plenty of warm amps being made today. I hesitate to use the word "harsh," though they sound harsh to me
But tube vs trad SS vs micro doesn't enter into it. There are harsh and warm examples all over the place. I hear commonalities of tones in each category, but they can be designed to sound any way you want, and many amps can do both harsh and warm. Some do one better than the other, but most amps are pretty versatile if you use the knobs.
