The Melbourne Ausio & AV Show is on today. I know there are going to be stalls from Noisy Motel and Addicted to Audio - not sure about other Head-Fi retailers.
It's on today, tomorrow and Sunday at the Rialto Hotel on Collins St (495 Collins).
If you come down, drop by the Noisy Motel stand and say "hi" - I'm giving Billy a hand.
I'll come back and post some photos later once I'm there...
