I presume that's only your opinion, daftee (based on relatively limited experience with them), not a statement of fact? One should always guard against becoming absolutist
I know where you're coming from, but there are some superb head amps around, which when used in the *right context*, can offer all the magic you need, and truly superlative results, which at some point you may get to hear, and after which may prompt further re-evaluation of the matter.
What does "sonically impressionable" mean, btw?
Anyway, the important thing is that, for now, you've found a viable solution that works for YOU, and that puts the whole SUT vs. headamp 'headache' to bed. In this game, the main focus should always be on the music!
