I wish that I or anyone else for that matter could give you decent advice about which speaker for Class D, but it is not possible. I use Bel Canto Ice-based amps for my VSA VR-4JR speakers and love them. But....it may be the tubed Modwright pre-amp, or the solid copper cables, or the PS Audio DAC, or the signal cables ICs, or... So, the synergy between all these electrical components is the key. Many listeners pair the Class D and solid state amps with tubed pre-amps and like them. Also, there is a lot of variation in the design of Class D and so the advice that would be most helpful is from those who already run the Nova and S300. Good luck!
