First off, what amps would be the best for the three players?
 
And how do they sound in comparison with their best amps?
 
I'm mainly looking for something that would be great for Electronic music, so what would be the best player for that with the best amp?

I think J3 really is what you are looking for..
Great sound,micro sd slot and if you like keeping your tracks with artwork the amoled screen really has amazing display..
Oops,i nearly forgot jet effect 3.0,it really enchances your sounds to another level.
I think X7 has great storage but for portable use is quite big.
