Hi. I have an X6 audio FX DAC, which is fine as a dac for my Breeze TA3116 speaker amplifier, but too loud for iem listening (generally low impedance and very sensitive as you know). I would like a similar combo, RCA output for the speaker amp and headphone output but that doesn't create a static hiss like my DAC does. I was thinking about the iFi Zen Dac V2. How do you think the DAC is compared to mine? I know that as headphone ampli should be good. Thanks
