Mcintosh or Classe

McIntosh.. U can't go wrong if you're staying solid state.

your ca-300 is 300 watts. if you meant 400 watts, classe has a ca-400 that is 400 watts. i use to own mcintosh gear and went all classe (ca-200,cp-60,cdp-10) and love them. i do agree with wireless200 that the older classe ca-200,ca-300, ca-400 models sound better than the current models. i use a ca-200 now which i will use in mono mode when i buy another ca-200. the mac 402 are very nice amps also.

Mcintosh 402 is the one of the Best sounding power amplifiers ever designed. Does everything perfect and you will never ever be disappointed. The MC402 is the smoothest sounding power amps I've heard in the past 25 years. Fantastic dynamics and extraordinary detail and soundstage.

I prefer Classe.

I own five Mcintosh amps. However I could be just as happy with Classe. IMO, they are about equal in sound quality but do sound differently. It's a matter of preference. I chose Mcintosh over Classe because of resale value. Mcintosh has the highest resale value of any of the components I have owned. The two ampa are different so you really need to hear the MC402 before you buy. Still, I think it's an excellent amp and you most likely will like it. The MC501 monoblocks are the ones you should get if you can budget them. They are a step above the MC402 and where I would have started if I knew what I know now. Which brings be back to a previous point, you will have little trouble selling the amp if you decide you do not like it.
