It may just be me but whenever I have the USB CHARGE set to ON, I lose the audio. This is a hassle because I have to charge it everytime I want to use it. Also happens when docked into the E09K. Any help? 

Yes they should be fine. Please update on the sound quality of the Q701s with the modi+vali. I considered this combo quite a bit ago.

I tried so hard to remove the inner plastic piece but couldn't do it. It took a while but I removed the tape without removing the plastic. :D   Now so far I'm loving the extra boost in the sub-bass and mid-bass without changing the highs and mids, but I did notice a slight decrease in...

Haha, I was going to get this same exact unit but decided to purchase the E07K and E09K bundle instead. I love the E07K when paired with the V-Moda M-100s. Great buy!

Quick question. Can I use this DAC with a seperate amp? (But wouldn't that be double amping the signal? Because I heard that's bad)

Thanks for the insights, it was very helpful. I've decided that I'm going to try the mod. Be right back!

Looking for opinions from people who have tried it regarding the bass mod by removing the plastic tape.   1) I know that I will gain more bass but what will I lose in exchange (soundstage, detail etc.)?   2) Overall, do you recommend doing the bass mod? 

Found a solution: I disabled the USB Charge option on the E07K while being docked in. Never had the problem since.

Can anybody compare the Magni & Modi stack with the Fiio E09K/E07K combo? I currently have the Fiio combo and might want to upgrade in the future. I use the AKG Q701s and so far I'm loving the combo.

Hi everyone,   Today I picked up a Fiio E07K + E09K for my Q701s and tested it. I had all the settings right for Foobar and windows and it worked perfectly until about 30 minutes after; There was no sound coming out of the headphones. Whenever I try to play a file I get this...

Yeah but first I put painter's tape to the area I'm going to apply the glue and the foam. So when I decide to remove the foam, I just peel off the tape and the glue marks will be on the tape itself and not the headband. 

    What I did to solve the bump issue. It looks a lot cleaner than wrapping the whole headband with foam. It's colour green too so it goes with the green theme of the Q701s.

Thanks. It was a good read but I didn't find anything that interested me.

I made the wooden stand at school with only about 40 minutes left in class. I had limited resources (but free!) so I'm quite happy with what it turned out to be. Total costs: $0
