Which amp should I get?

I just had my amplifier die on my (it strangely turns on, but no sound comes out). Anyway, I'm looking for a new one and I've found that the KAC-7204 and KAC-7205 are both good, cost about the same, and have the same ratings. Anyone know what the difference is and which is better? Evidently the KAC-7205 has a higher fuse rating (2x30 as opposed to 1x40) and does not have a high-pass filter like the KAC-7204 does. This makes it seem like the 7204 is the way to go, but I see complaints about overheating there where the 7205 doesn't seem to have any. Anyone have any experience with these and any insight as to which is better?
