I'm not signing up for this, but would like to urge HiFiMan to exercise some greater discretion on adding people to the list. I see people on the list that have very low post counts combined with no feedback, and while it's certainly true that everything could go smoothly, Murphy's Law says otherwise.
Justin of HeadAmp has run similar loaner programs in the past and he recently instituted a rule to the effect of people having been Head-Fi members for at least 6 months and at least 1 positive feedback. Or something along those lines, I can't remember exactly. A similar rule for this tour would likely be beneficial for everyone involved.
