I agree with Tok20000; 1) Do not expect low freq control with the Monarchy se100 monos and 2) That the Krell runs too hot.
I disagree with Winoguy17 about the McCormack DNA. I find the sound too similar to the sound of the Marsh 400s. (I just don't like it). You'd be better off with the Musical Fidelity A3CR.
I have owned Bel Canto EVO 200.2's and now have two PS Audio HCA-2's. I needed both Bel Canto's and I find I only need one HCA-2. The most low freq control and non-colouration of sound comes, hands-down, with the PS Audio HCA-2.
I have never heard the Rega exons.
