CAT vs. Aesthetix vs. Supratek - Preamp Choice

Hello All - I'm looking for some advice here. I want to upgrade my Modulus 3a with either a Supratek Chenin, and Aesthetix Janus, or a CAT Ultimate Mk 2 - and could use some advice. My system is linked below (I promise to respond to questions soon - and cut me a break Marco!) I am looking for something that images well, is dynamic (don't want to lose dynamism with Quads), and is just overall musical. Has to be a full function preamp (phono included). Remote is nice but not a requirement.

Can those with experience provide some thoughts on the difference between these preamp flavors? Good advice is highly appreciated!

Thanks, Peter
