The only thing you can really do with any of these new switching amps is wait for the reliability information to slowly flow in. Agreed, for the Carvin BX500 and the GK MB2, it has not been too reassuring up to now. These things will be worked out. These amplifiers employ a technology that appears to be new to these manufacturers but in time they will get it sorted.
My personal opinion is that at this time I would not use one without carrying a backup - for that reason I will not buy one. That said, I am confident that in time the negative reports will taper off. Then I will buy.
This is good advice, but I feel that if a manufacturer is putting a product out for sale, the beta-testing should be over already. If I take your stance then it becomes obvious that these companies are using paying customers as product testers. It doesn't inspire confidence, and I'd like to believe that isn't the case.
