Need suggestions for speakers for Classe system.

Hi Everyone,

First and formost, I would like to say hello. This is my first post and looking for some good advice.
I'm hoping someone can give me some suggestions for speakers which would mate well with a Classe CA-400 amp and Classe CP-65 preamp. I am currently using a set of Paradigm S4 v.2. They sound great with fantastic detail, but I think they are a little too polite in the upper mid range on some recordings. They sound great when powered with an Anthem or a Parasound. I'm sure it is due to the laid back, smooth nature of the Classe. Has anyone had any experience with this type set up with satisfying results? I also have a second CA-400 I could use to bi-amp or run as mono-block if needed. My IC cables are all Synergistic Research accelerators (Balanced), and my speaker cables are Transparent Ultra Bi-wire MM2. Any and all suggestions are very much appreciated, and thank you in advance.
