I wouldn't say _need_ to spend money, but I am looking at my end game headphones + amp and I realized I never finished modding my crack. So I want to see where I land with it before making my end game (will stay at home) setup.
I considered a crack-a-two, but I might also be having someone build an amp...
Anyhow, the idea behind the audionote was to find the not-cheapest-upgrade, but not most expensive.
I'm not sure I've read a lot about the TKD yet, just the audionote, blue alps, chinese ebay ones.
