I like the idea of a custom and the price is definitely reachable in the Freqs and Livewires. but honestly I've never heard of refit problems from UE or Westone for their customs like these 2 new players. So much so that its probably slowing production for new users with all of the refits that keep getting sent back. A month long wait is just unreasonable in my opinion.
I was thinking of upgrading to SE530 from my UM2 but it seems that there isn't much of a leap in sound quantity. Who knows.
