i'm sorry but i have to disagree with folks that feel they need very expensive monitors. a recording engr in LA put me on to this when i saw him mix years ago on small monitors and a variety of playback mediums.
he was using auratone cubes, home hi fi speakers, NS10's,phones, earbuds,
mono spkrs, car speakers and checking his mixes on each one.
he knew way more than i ever will in this life. what i basically learned from him was there is no perfect monitor no matter how much money one spends.
so i would suggest to mirrors a combination of what he used to check his mixes with.
and maybe a pair of yorkvilles.
no flames please -mthis is just my personal opinion.
ive also had extensive discussions with AES folks more knowledgeable than i on this issue. as always though even the AES pro's disagree with each other as well i found !!
