Even knowing that Gouda is best and Feta is worst quality, and having read comments about "listen out for sibilants and hi-hats", I can't hear a difference between the two. Maybe it's time to de-wax my ears. And to those saying that "storage is cheap, I can fit all my FLACs in a 500Gb hard drive", I say "show me a portable MP3 player with 500Gb of storage".
