RSA Protector + ES5
JH-3A + JH 13/ 16 Pro
RSA Protector + UE18 Pro,
 
Which combo is the best?

Um...I'm not sure, but if you have all those to choose from, I'm really jealous right now!

That question probably cant be answered. People having either iem would 9/10 not possess the others, or even other amps. Taste is subjective moreover. Therefore till the end, its unjustifiable which is better, let your ears decide.....after your purchase.LOL

I dont think anyone has gotten the JH-3A yet.  I know some of the guys have listened to it at Can Jam so it might be a little early for this type of question IMO.

JH-3A + JH 13/ 16 Pro should best them all because the bottleneck of these high end custom IEM's has been fixed. That bottleneck is the passive crossover. Though don't get me wrong all of those combo's listed up there will provide awesome sound.

JH 3A, with the active crossover.
