Hello brian brock. Excellent advice. I had a bit of a play with a friend's RX4 and, yes, I agree, the Dialog De-Noise was amazing. The RX4 or RX5 suite are certainly on my radar as is T-Racks CS Grand. I wonder if either will do a better job than a hardware device such as the DBX 286S. In some ways, I hope not or I have wasted my money on the DBX unit!!!
