[siess]

I am looking to purchase the ROC SA to go with the Ref 5 DSP and am trying to find out if the amp hisses with iems - or more specifically JH16's.
 
I have portable amps I use with the 16's (Pico Slim & RSA Protector) but would also like to use them with my main desktop amp.
 
I would run the 16's balanced.
 
Kingwa has not been able to give me an answer but suggested I also ask if the FUN or C2 hiss with iems as he says that both have more noise than the ROC SA.
 
Thanks
