I'm staring to find that out!
So some questions. I have the E09K and E07K connected in my office right now to my laptop. Everything seems to be connected correctly. I'm a little upset volume on the E07K still works and actual does manipulate the sound. It seems like that should be something that is immediately disabled when you connect it to an E09K. I have it turned all the way up to 60 and am just controlling it through the E09K. Anyway, I can run my SR325is and DT 770 Pro off of them and they sound ok. I've even thrown some Vmoda Vibe IEMs and Porta Pros on them and they were ok. When I run my PX 100-II off of them, it's just a distorted mess, the volume needs to be fairly high to hear anything at all, and separation and stereo go away completely (everything is mono). I verified nothing is wrong with the PX 100-II by connecting it to my phone and headphone jack on the laptop directly. Sounds great through there. I thought maybe it's a sensitivity issue, but the E09K is suppose to support cans between 16 Ω and 600 Ω. The PX 100-II is 32 Ω.
Why is this happening with just this can?
