But any decent buffer is itself quite transparent in terms of its voltage transfer characteristic.
This is complicated by the fact that many buffers are less than well designed. While that's true, it's not difficult, as you know, to design one that is essentially an impedance converter, making the same signal able to drive cables without loss. This restores the guitar to what it would have done without cable loading, but it makes the true-tube-believers say "too brittle" automatically, even if they've been complaining about loss of "tone" in their setups. "Loss of tone" is most closely translatable as "treble loss from loading". But sometimes it can be used as "brown sound" or "vintage sound" if they're trying to be complimentary.
The fact is, once a person decides only a tube will do, only a tube WILL do. They will actually hear other alternatives as worse somehow, in a poorly quantifiable way. It's not that they're being obstinate, just that their brain is interpreting things below their conscious layers of thought. They think it will sound worse, so it does. And there can be no argument about whether it really does sound worse to them or not - it does.
The other side is that the favored approach will sound indefinably better. If sound through a tube is the only thing that sounds good, then sound through any tube will sound better.
This is a trap the human brain seems to build for itself. Many fortunes have been made in the hifi/stereo world based on this. The subjectivist underground has almost made itself into the majority this way.Amazing!! Who would ever have guessed that someone who villified the evil rich people would begin happily accepting their millions in speaking fees!
Oh, wait! That sounds familiar, somehow.
