I have a Mackie 1640 and I love it. I upgraded from Motu 828 MKII and Digitmax LT. Very nice and clear, but I need some thing with a nice warmth to it, but I'm not saying the Onxy are cold by any means. Are the RNP in the same ball park as the onyx pres? Would the RNP be an upgrade in quality? Yes I understand different preamps give different textures, but thats not what I'm asking.
