Hi Guys. Got myself a Grado SR60i. I'm just wondering what path to take first to further enhance this set of cans. Here's my options as of now: Option 1: Buy Portable Amp(Arrow or JDS Labs cmoyBB/c421, etc..) Option 2: Buy Woodies from Marty(+Liberated) What do you think guys is the best in terms of price performance ratio? Thanks!
