Westone 4R hissing sound..??!!!

Earphones wont produce hiss on their own. They only put out what they're taking in... in other words, it's more likely that it's your source and not your W4's. Have you tried plugging different earphones in to see if the hiss is still there. Or tried plugging the W4's into something else?

Do you think it might be the power/electricity from my imac? do you think a power conditioning will help?

It's most likely your computer. Have you tried using the DAC portion of the E17? Use the USB cable that came w/ the E17 and plug that between your mac and E17. You might also need to go to system preferences -> sound, and then make sure the Output is the USB DAC. If it still has hiss there, it might also be due to the E17. If that helps it, then I would then try using another amp to your doc (if you have one.) This would be the best way to isolate and confirm that the hiss is from your computer alone. 

When I plus my IEM's into my macbook pro, I get tons of hiss, so i always have to use a DAC/amp with it.

How is this happened?

 

 

Thanks
 

Honestly, I'm not sure. From what I understand, the E9 dock is its own DAC and bypasses the DAC in the E17. I'm thinking the E9's DAC is faulty... or you're somehow not using it and it's using the mac's sound card (which is hissy.)

I would maybe try contacting FiiO about this and tell them what's happened and maybe they'll send you a new one? It's worth a shot.

edit: My apologies. I don't really follow FiiO products, so I assumed the E09k is a DAC. I just looked into it a bit and it's actually an amp. Hopefully someone w/ more experience with FiiO docks can chime in and help... but I'm assuming since it's an amp, it only needs the E17 for its DAC? If that's so, then it's somehow causing your E17 to not use its DAC and using your computer's sound card, which is giving you the hiss. Either way, I would contact FiiO and tell them that you're getting a bunch of hiss, and that the hiss goes away once you only use the E17 as a DAC/Amp, but it comes back when you use the E17 + E09K combo. 

Sorry I couldn't be of more help. Good luck!

No prob! Let us know how it works out after you talk to FiiO.
