Meh, you'll never get me acclimated to the types of tracks most people listen to. Nor do I expect most others to feel the same way about my music, regardless of genre or how well it's recorded and mastered. Very rarely can I judge gear with tracks I'm unfamiliar with AND don't care for, which is key (I gotta be able to get into the music), unless something is clearly off with the gear. I got HC from HFO and still don't get as much use out of it as my usual, generally crappier sounding tracks. Though it is useful in some ways, yes, and I'm happy I got it now.
I prefer everyone just bringing their own music and dumping it on everyone's machines so they can judge with what they're used to. Worked well at the Boulder meet, save for some initial confusion and learning each other's machines, software, and directories where music is stored. Otherwise, I put something on, nod my head a few times, say, "Mmhmm, mmhmm...yep...No idea what I'm hearing." Again unless something is WAY off. Like the HE560 for my ears.
However, I am open to keeping this group-agreed-on music on my machine for meets and so I have a frame of reference when reading other folks' impressions.
In other words, I'm a stubborn ass and have nothing to contribute because most of my music sucks for most everyone! (But will comb through this and get some new music on my machine for the next meet.
