Classe CA 301 vs SIM W-5

I have just purchased a w-5 but actually wanted a ca-301 but the price difference was $550, I have not received the unit yet and am a little skeptical on the w-5 because I have not heard the unit before, I have heard the classe and liked the sound, has anyone compared them directly, my system consists of b&w 804s bryston bp25da sony scd-1, any comments would be greatly appreciated thanks.
