After having read many positive reviews of the FX-Audio DAC-X6, also within this forum, I decided to give it a try. It arrived today and works brilliantly with my Superlux HD668B. However, I'm having problems driving IEM's.
The main purpose of the DAC was to improve audio quality over the very cheap USB to 3.5mm connectors, which I had been using ever since the headphone output on my laptop broke.
The DAC works brilliantly, except when driving IEM's. I have tested both the KZ ZS-6 and Brainwavz R1, currently the only IEM's I have at hand, but neither seem to work properly in conjunction with the DAC. The vocals are muffled, almost completely being drowned out by the instruments and near inaudible. The songs also seem to be played in a slow-motion kind of fashion, at a slightly different pace than normal. I have no problem with either of the IEM's when using different external amplification or when connected directly to a phone.
My question; is this normal? A DAC should be able to power both headphones and IEM's right? Is my unit not working properly or am I trying to do something that simply isn't possible?
Hey, not sure if you've been able to get answers to this yet.
The problem with is with 4-pole audio jacks, so you have to buy a splitter (splits the output and input channels). Learned this the hard way with my HyperX Clouds and my KZ ZS-3s. Not sure if it's the included adapter, or the audio port of the DAC X-6 itself.
