I haven't seen any claims that the cheap ADK should
be any more vintage than any other mike. But you
may be right. I have the TSM and at least mine is
ok, but as you probably know thats says very little about
the one you'll get.
I've tested it mainly on vocals (3 guys & 3 gals). I found it good
to very good on male vocals, but a bit tricky to use on some
female voices. It was possible to get a good sound, but I had
to try things like not singing into the microphone, angle it etc.
Not my first choice there, which is a pity 'cause I bought it to
try on my old lady.
I've also tried it on classical guitar. Alone it was ok but not
exceptional, running in pair with
a Neumann KM84 it was
fucking incredible. Pure magic. They complemented each other
very well.
Of course, these opinions are my own. And I am NOT a guru.
