What would be a great purchase between either Brainworx bx_masterdesk vs Waves Grand Masters Collection?
Waves Grand Masters
Linear Phase EQ
Linear Phase Multiband Compressor
@Borrowdale Barron, it seems that you think Brainworx's bx_masterdesk is supposed to be used by serious professional audio mastering engineers.
I'd suggest you consider it as something like IK Multimedia's Lurssen Mastering Console—you will gain a reasonable understanding of the crowd who will regularly use it after have done what I said.
By the way, Brainworx now has a new maximizer i.e. bx_limiter TP (True Peak), you should check it out.
