I am currently looking to upgrade the way I mix music. Currently, I have a fast track ultra and I'm just using a pair of 50$ monitor headphones. I have done test recordings of 16 bit, 44.1 Khz Vs. 24 bit 96 khz recordings, and I cannot hear a shred of difference. (I know my fast track ultra is capable of recording that bit rate). So I'm thinking it's the fact that I use crappy headphones. I would like to buy a pair of really nice monitors (Budget of 400$ max), but do you think I'll be able to hear much a difference in monitors that cheap? Or will I need to save some money and go all out on a pair so I can really start mixing better? Thank you for any help!
