So there is a metal band inside its headband? If so you just wrap it with some protective fabric and forget about it :D

Has anyone ever tried to diassemble ex1000? I want to repaint/refinish my heavily scratched housing.

Has anyone shorted that 4 resistors? I think that resistors are for hiss-reducing purpose.

Anyone knows the output impedance of Zishan DSD with stock op-amp ? P/s: nvm, i have found that around 20 Ohm with stock op-amp

I can clearly hear the hiss with it04 from balanced port (smaller when set to low gain)

Im still burning in my dx120, but with more thickness its really match zx300’s smooth midrange. Dx120 is more like reference sound while zx300 is more rounded, personally i still like zx300 more due to its comfortable sound.

After almost 24h burn-in, my dx120 sounds much better with more thickness and clarity, perfectly match my IT04. Im very happy with the sound.

Yes i use balanced port. May be i need to burn in with that burnin cable for a while and check if it has any changes in sound.

Ive just bought a new dx120 from shop and have a quick a/b test with my zx300, iem it04. First impression i heard that zx300 is much more musical with more sub-bass and thicker midrange, or even better seperation. So do i need to burn in my dx120? I choosed super slow roll-off and natural sound...

Thank you for your info, ive just stopped my R3 order and back to my old Cayin N3 for the stack :D

I'm going to buy Hiby R3 as a digital source for mojo but the RF problem is setting me back. Can i ask you if i have leather case for both device, will the RF happen ?
