Tube amps are amazing for distortion effects, no doubt. But for a 1-to-1 reproduction of audio signals, it's not great.
LPs are a slightly more interesting discussion IMO. Objectively inferior to Redbook audio by a mile. But, given the 30-40dB noise floor even in a "quiet" room, and the THD added by the loudspeakers, I think their real-world performance competes very very well with digital audio...
