yeah for me it's very important that you do drastic mastering changes from your end and then let ppl such as curvepusher add that final sheen ontop. at the end on the day, you don't pay the cutting place to drastically change your sound into something it wasn't meant to be!!!
it may be of interest but once i sent a blackout release to a specialist mastering place first before the cut. when i phoned up lawrie he said it was awful. he really had to work to get it right. apparently most mastering places don't understand the difference between cutting to vinyl and cutting to cd. the stupid ass had widened the whole stereo field.
