Best 5 channel amp?

[Idunhaveone]

So I've been looking at the U.S.Amps 5600x, the Zapco Reference 650, the PPI PCX 5800 and some other 5 channel amps. What do you all think the best 5 channel amp is, of these, or any others?

Thanks

I have a US Amps 4300X and a 700T, both of which has throughly impressed me for power to size ratio. So, I would whole heartedly recommend the 5600X. However, the other two are puportedly good brands as well with plenty of quality feedback. So, tough choice.
