Got Ears?

I'm wondering how quickly you develope your listening. I'm sure my ears are more in tune to pick up the little nuances in a high fidelity system than when I started this madness 9 months ago. Thanks to alot of you on this site I learned what to listen for, but I know that I still have alot to learn when it comes to picking up on certain things. Do you guys (and Elizabeth ;-) think that having an ear for audio is something that just continues to develope and develope? I feel that it's an important part to fully enjoying this hobby as it allows you to enjoy a well thought out rig and your music collection to the fullest. I'm fully enjoying cd's that just this time last year I would have only used as coasters or made fun of you for listening to that "crap". I can't help but think half is my rig, the other half are my somewhat trained ears. If I tell my girlfriend, who by the way grew up in a musical family (dad was a music director for years at a major university) and plays violin, guitar, sings and has perfect pitch, about how an improvement to my rig deepend the soundstage, brought out shimmering highs with faster attack and longer decay she cocks her head a bit and says "huh?". Anyways, have y'all noticed your ears getting more in tune with picking up all the things that make an audiophile an audiophile and if so how and when has that happened?
