Confused about Krell FPB 300 400 200 Amplifiers

I have auditioned a Krell FPB-300 and an FPB-200. There was a large difference between these two amplifiers. I am in the market for a new Krell amp, but I can't decide between the FPB-300cx and the FPB-400cx. I understand there will be a large difference between these two amplifiers. However, I would be satisfied if the FPB-300cx performed as well as the FPB-300. So, I have two basic questions:

1) Is the FPB-300cx comperable to the FPB-300?

2) How much benefit is there to monoblocks.

Any and all input will be appreciated

Thanks,

Dual power supplies will give you greater separation of the signal and ensure that you have no "bleed-over". They will also allow you to plug into two separate AC circuits if you have them in your room (just have to be careful about creating a ground loop). Finally, the output of two power supplies will likely be greater than if the designer had to use just one larger one due to size/weight and manufacturing issues (harder to manufacture a precision 3000VA transformer than two 1500VA ones). Probably some other benefits also (electrical field density, "speed" of smaller torroids, etc.).
