I do most of my work on computer although lately I want to rely more on my Alesis Ion synth as well as add a Dave Smith Instruments Mono Evolver Keyboard.

I was planning on buying one of each, but now I'm wondering how dramatic the difference is between them. I get the impression that the RNLA is just a more colorful version of the RNC, but maybe I'm wrong. Any thoughts?

New Product from FMR Audio.
It is the RNLA Really Nice Levelling Amplifier (colored Opto).
It's going to be $225 street. Here is a preview.
