I love the sound of ipc+minibox e+er4b, but accidentally I lost them last month. So I deside to build a new portable system which sounds better.
I bought a imod (4G) as source, and hunt for another er4b.
Now I'm asking you to give some suggestion about the amp.
I heard the JDS Labs C421 and Leckerton UHA-6S MKii are both A+ amps. So which one is better for this system?
Thanks a lot.

Well, I think the C421 is a good amp, but if you can justify the cost the Leckerton is ultimately the better amp (to me). I also wouldn't rule out the UHA-4, I prefer its sound quality to the C421, its cheaper then the UHA6s and has a dac section as well!

Thanks Kez1a for your reply.

I notice that UHA-4 has a function named X-FEED which can decrease the dental sound. In my oponion, it's useful for some IEMs especially the er4b when listening to some vocal music. But I can't find this function in the later product 6S-mk2. Is that means it make the sound bad and Leckerton has given up this feature?

Wait for the JDS Labs C5 as it has no channel imbalance at any volume, is smaller than C421 and supposed to be a big upgrade
