Aphex 230 simply awesome

I purchased the Aphex 230 and this has to be the best all-in-one solution for voice work I've encountered. I use an Electro-voice RE-27 dynamic microphone and this unit really makes the voices behind the mic shine. With its easy to adjust compression, noise gate and de-esser, as well as the effects section (big bottom, parametric equalizer, and Aureal Exciter) this unit far surpasses anything I've had in the rack. If you're in the market for a unit of this type, be sure and look seriously at the Aphex 230 before you purchase, you'll be glad you did.
