What is meant exactly by the description 'more musical'?

 Oops, I think that you may be the one that's wrong! I'm sitting here listening to Sacrifice (thrash from 1987) on tubes and high efficiency speakers, lol. Sounds glorious!

@newfzx7  , I did stipulate that this is what "I think", meaning that I could be wrong.  Are you using a SET amp and how many wpc does it put out and how loud do you do your thrash at?  The SET folks I have talked to (except for the ones with higher powered SET gear, such as the Cary 805s or 211s) tell me that they didn't go the route that they went because they wanted to reproduce loud music.

@newfzx7 +1

When Rocky Mountain AudioFest was running I was regularly visited by a group of local metal heads at that show. I would play something for them and  they usually had some LP for me to hear as well. 

There was a reviewer who was also into metal who would also play faves of his in our room. Metal heads appreciate good sound like everyone else.

@atmasphere  , I am not saying that you did not have this experience; what I am saying is that 14 or 15 wpc of SET would not have done it for the metal heads I used to know.

@immatthewj that would only be because they didn't have the right (more efficient) speakers to go with it. So that would also mean that someone into classical wouldn't be satisfied either unless they got more efficient speakers as well.

@atmasphere and @newfzx7

. . . and apparently by some SET standards, 14 or 15 wpc is a lot, as I keep reading about some of Dennis Had’s new stuff making less than 5 wpc? I DEFINITELY don’t think that would satisfy the average metal head.
