Yep but the waves mercury bundle is around $6,000 alone, not that higher price = better but they are absolutely the most useful tools for masterings Ive ever came across.

I'm not a professional sound engineer but I do know how to use them and Id be glad to play around with any of your tracks. Just to show you how some proper mastering can really bring essential depth into the mix.
If you ever wanna do it I just need each instrument/channel rendered as seperate wavs preferably 24bit. Only because metal unlike trance is one genre that benefits A LOT from mastering. Trance has a lot less recording going on so a lot less room for inteference/phasing and all that good stuff.
Just let me know!
