thank you for your time, anyway, Brooko.   I just installed the Mediubuntu repository and added all the the plugins for low latency sound cards and USB devices. The sound quality seems different but I still hear a lot of crackling sounds.

Hmmm I guess I should have given more details- I have been using my E7 since I purchased it in October. I did experience crackling sounds on another PC and spent days troubleshooting, until I updated to windows 7 service pack 1 and the issue seemed to fix itself. On every other laptop or PC that...

I'm using a USB cable and selecting USB audio DAC from the hardware options for sound.

I don't know how to check either of those things. I'm looking it up right now, but I wouldn't mind if you told me.    Thanks.  

I don't know. I installed linux partly because I did not have a windows CD, and I had been given the laptop, pre-owned 

Sigh... Just realized I can hear it, even without the DAC. The crackling is just a lot quieter. I guess I can blame this crappy laptop.

      I have recently installed Ubuntu 10.10 on a netbook (eee pc 1201ha, no graphics drivers yet for 11.04). When I tried playing music from my Fiio E7, I heard terrible crackling sounds mixed-in with the audio. Just to make sure it had nothing to do with the audio format, I tested...

Thanks. I feared that this was the case. I'm going to flash my motherboard's BIOS. If the company that designed it has updated the firmware to remove any bugs related to audio, this could fix the problems. Otherwise, I guess im out $150 for a new one :P (or at least an audio card)   also,I...

Quote: Hey Shabs, were you able to diagnose the specific problem with your E9? I have been hearing crackling on any type of audio file, including youtube videos. I was worried that it was actually a problem with my new beyers, but after trying a different pair of the same model, I was...

never mind this post. my concern/question actually relates to my headphones

Quote: lol. the -90 on the surface of the E9 is for the volume knob. At the lowest setting, the volume is playing at 90 db less than the actual source volume coming into the amp. The zero on the other side is saying that there would be no limit placed on the amp's ability to drive the...

              

I strongly recommend that you order from Micca (if you can). They offer the combo discount, have fast shipping, and have great customer service, too. Also, Jack, a store representative hangs out on Head-fi, so you can always talk to him if you have problems. It is very easy to get scammed on the...

Thank you very much. I hadn't realized. (the diagram did not make this clear enough for me.)

I seem to have run into some problems with my E9. Lately, I have been using the 3.5mm line-in port to connect it to my source, but after moving it to my room, i have tried connecting it to my PC to use as a DAC. When I plug it into my computer using the usb cable, it does not seem to be...

The question I had was answered in another thread. I just want to point out that in order to use the E7/E9 as an amp and DAC, the E7 has to be on, even if it is docked. (the red charging light does not indicate that it is on, only charging)

Hi. I am currently using the Fiio E9 with a pair of dt880 600s and they are definitely being driven very well. I would not recommend powering a 600 ohm pair of headphones with the e7, though. It is noticeable that they are not being fully driven, but they still sound decent if you crank up the...

Wow, and I've been picking at it for like 20 minutes :p   Carry on then.......

Hello. My E7 E9 combo came in the mail today. This is the first time I have used an external amplifier and I am truly blown away by the sound quality. I ordered a pair of Beyer DT880s just for this occasion, and they sound spectacular. I un-boxed everything just several minutes ago, and while...

I just ordered a Fiio E7 E9 combo from miccastore.com for about US $200. This store is listed as an official retailer on Fiio's website. Shipping was free (for orders over $99). Also, their customer service seems great, too. I asked them a question about my order and I received a positive reply...
