I think the main point in using tubes today is to have them introduce distortion. If circuits with them sound ordinary and clean people would likely just think the tubes are broken or in there just for show. You know, you've got to hear that tube sound, right...?
If the intention is clean sound reproduction you might as well just use an OpAmp that introduces less than 1% of THD.
So, I figure that for modern applications of tubes the starved plate voltage is a actually a pretty good solution.
I was not saying that you light it up with LEDS, but some people do.
Tubes compress and distort in a more musical way than anything else.
