I sent my pico slim to Justin for the warranty repair. Its already 6 months, I didn't any answer from him. I made few calls to headamp every time he always said oh I forgot I will sent out next week. And now there is nobody to answer the phone or my email. This the worst customer service I ever...

  This will be the last post that I will write on this thread, because I know my subject is irrelevant with GS-X. And I don't want to get banned, but this is the only way that I can communicate with Justin.   1. i have several items to go through (batteries, headphone jack fixes) as soon as I...

Hello Headfiers,   I am really sorry to interrupt your discussion on this thread, but I have no choice to do this. Because I tried to call Justin more then 20 times (left message and now his voicemail is full), sent him 5 emails and wrote on his facebook 3 times. I got no answer from him.    ...

I mean does the music volume affect the battery consumption of the DX50?

1. The battery will be drain faster If you are running DX50 at full volume (with an amplifier)? 2. Does DX50 gain do any difference when it connect to any portable amplifier?

I received my upgraded C5D this week and used for 2 days so far so good. I want to say that JDS Lab have the best customer service.   Thank you John   

So in general, if you want to use the dac, you have to switch to CHG mode first, then turn On your C5D. After you can switch back to BAT mode if you use it with any portable devices. Am I correct?  One more question for the bass boost switch which is off med and high? For example, if I place...

Today I just bought CCK for my itouch 5g. I have to switch to CHG mode to turn on C5D to use the dac (after I have to manually switch back to bat mode). When I turn on in BAT mode, the music will play out of my itouch speaker. Its the same story when I plug it on my Macbook. But you said you are...

I got this pic from my itouch 5g wallpaper (which is almost same size to the amp) photo galary, and then I converted the colored picture to black and white. You can always send your engrave picture to JDS lab to ask them if its ok.

I just received my C5D, and I am charging it right now. When the amp is fully charged, the blue light will turn off? If I let it charge over night, the amp will be overcharged or it will automatically stop?  Nice engraving.  

Modi+Magni is a good combo for grado sr225 or shure 535? All the schiits headphone jacket are 6.3 or 3.5 mm? Where I can buy Schiit in Canada, or I have to order online from USA?

I searched in this thread, it seem grado sr225 is not very good with Vali? 

iBasso DX50 Leather Case Colors: Dark , Blue Price: $30 Global Shiping: $10  to $45 Accept payment via paypal: phuong@ido.com.vn Online orders contact: phuong@ido.com.vn   http://tainghedunu.com/p-1032-ibasso-dx50-leather-case.html   What I found earlier, however I don't know its safe...

This is a leather made in Vietnam cost around 35 to 40 dollars. I saw on a singapore site. 

This is the same case that I got from ebay, but I dont know mine is 8cm or 10cm.

If you live in the canada, you can buy oyaide cable from Headphone bar.

You got the idea. 

JDS can engrave a picture on your amp? Any1 can show their engraved C5 or C5D. Thanks 

For me, HD25 is like AK47 and HD26 is like M16. I hope you know what I mean.

In my opinion, you should try to buy from your local dealer, because its more easy for exchange or return.  (Maybe you can post a photo of your amperior with oyaide cable after you bought it. )

Fiio will release any new firmware for X3 in the future? 

Whats the difference between C5 and C5D in the amp section? They are the same or C5D is better than C5 as an amplifier. Since C5 is made for earphones, that means it cant drive my sennheiser hd 25 (70 Ω impedance)? How the sound signature is different from pico slim?   Thank you if any...

1) You are right, its not a hard case. But I think its good enough to protect your headphone in your bag.(If you dont sit on it lol)   2) For the cable, Oyaide is a well know japanese company, and all their cable is made in japan I believe. So if I were you I will choose Oyaide.    I found...

Any1 use C5 with shure 535, is there any hiss? 

Personally, HD25 is very good with amplifier (with my Arrow 3G or ibasso DX50) and the Amperior is made for all the regular mobile device (phone, mp3 player and pad).
