I've sent an email, and I am waiting for a reply. There is a constant hiss, I've tried many sockets, surge protectors, even a UPS source... even swapping cables. I live in an apartment complex right now... there's probably enough routers in here to give everyone in a 3 mile radius cancer. This happened before the jumpers. Hopefully Kingwa can help me figure this out, and I won't have to even think about returning this product. Also, I can only hear distorted music playing when using digital inputs. I'll keep searching for answers.
Sorry jodgey4, I definitely never experienced any distortion in music whatsoever when using the digital inputs (or any of the inputs). There is definitely something not right going on. I would have immediately contacted Kingwa if that happened as it was pretty much brand new while I owned it. And I never experienced any sort of hiss either (but never had any IEMs with this unit). Are your IEMs fine and sound normal on all of your other sources? EDIT: I just noticed that you were experiencing the noise problem with your LCD 2.2's as well, from your previous post/review of them.
It's very strange that you can still hear music and/or hiss even with the volume at zero. Not normal at all. Uhhgg...the one apartment I lived in years ago were horrible on the electrical/power, and they were fairly new construction at the time. My UPS was "blurping" at least a few times every other day! I'm almost certain it saved my Mac Pro tower with outboard RAID disk array, TV, and stereo gear from meltdown. I never had any real issues with power anywhere else that I lived (except maybe in Puerto Rico, LOL).
LOL regarding the wireless router radiation there! But it shouldn't be a problem for the NFB unless one is very close to it...say 2-3 feet or closer.
FYI, I was also using the EXACT computer/source setup that kkcc described...never had any noise or distortion either.
I really hope there is a simple solution. Let me know what Kingwa says!
