Yup, that's what i did the last 20 yearsBeatport wrote: If you're doing it yourself in a home studio then "mastering" is not the correct term. Even an entry-level mastering studio uses $15k full range speakers (not nearfields) and a highly trained professional that can hear a 1 db bump at any frequency. IMO, if you're serious about your EP, pay the $300 and send it to a pro. If you have a good mix, the results will really shine and give your track a pro sound.
One of the best masters i got back, was comming from Simon at the exchange (london). it was a huge difference.
