I’m running AES into a Waves MaxxBCL.
Waves D/A is transformer based mastering grade, it sounds absolutely incredible!
I bypass the Qu compressor on my mains and use the Renaissance Compressor instead.
MaxxBass around 38Hz, 60-70% gives a nice thick low end.
Then the L2 to brick wall limit.
I don’t think it’s possible to get a better setup at any price for something so compact.
The Qu has great conversion already, but a high end D/A really does make a difference.
