I think there are two things going on here.

First, the widely-admired DHTs (300B, 2A3, 45, 845) are in fact among the most linear triodes available (see my comments below about "linearity").

Second, I too have observed that in too many cases to ignore, there is a subjective "magic" (for want of a better word) to directly heated cathodes. Some directly heated pentodes and/or beam tetrodes are not very linear when triode wired but still sound better that those with indirectly-heated cathodes.

I can't claim to have heard a statistically-meaningful variety of such comparisons; I can't even claim to know how many that would be. So YMMV and all that. :^)
