we've been mixing for a couple days now, and i wanted to write a bit about the experience.
overall, i'm extremely pleased. besides the new room, this is the first i'm mixing w/ the pieces i picked up recently: adam a7's, api 2500 and a folcrom. this combo is pretty kick ass, i must say.
before, mixing ITB, i'd always get to a point where adding a track to the mix would start The Collapse -- each track would make the song smaller overall, and it'd be a fight to carve a space sonically for the new track. with the folcrom, even after adding (say) a new backing vocal to 20 other tracks, i can hear it and place it properly. love love love it.
so far, i'm using the 2500 exclusively on the mix buss. typically, i'll get the kick, snare and bass happening before i enable the 2500. everything else is mixed into the 2500. i set it to take off just 1-2 dB, so it's not noticeable -- until you get the whole mix going and hit bypass. then the balls just drop off the song. so i'm loving what the 2500 is doing.
regarding the a7's, the mixes are translating very well to both my home and car stereos, even after being subjected to the mp3 encoding of itunes. the high end, in particular, is sounding quite nice.
