verdict on class D amps?

I saw a thread about seymour ice amps.... anyone have any experience with these compared to conventional amps? I was planning on picking up a used pair of bryston 7st or a single 14 st however for similar money (& power) the new ice 50001 is available. In car audio there it doesn't seem like class D is very good except for sub duty. Is the same true for home stuff? Presently I have a adcom GFA5500 which was going to get thrown on rear surrounds & I was going to use parasound HCA1500 on my speakers untill I can afford something newer/better for my old infinity kappa 8.1 speakers

thanks
