Probably someone who really likes tube amps.

Many audiophiles scoff at "digital" music, i.e. audio that is amplified with silicon transistors.

Modern transistors are very fast, so noise that gets through the filters typically sounded like sharp pops and hisses. With older (and slower to respond) analog technologies, unwanted noise gets smoothed into more pleasing hums and modulations.

These days, there are excellent affordable digital options like the O2 amp. But it would be a boring world if we were all the same.
