OK, thanks. I knew I can't use X1 as DAC but I would have like to use the NFB15's DAC with X1 as source. Too bad.

Hi,   I planned to buy an Audio-gd NFB15, but can I use my X1 as source through USB ? The NFB15 doesn't have RCA input.

OK, thank you.   Yes it's a class 10 (this one). I've put ~40Go onto it so it took about 30min to transfer while directly plugged in the reader of my laptop.   I formatted it in fat32 (under GNU/linux with gParted) but I think something went wrong.

Hello,   I've just received my X1. My 64Gb card has not been recognized so I formated it with the X1 and it's OK. Now I'm transfering my music onto it again, it's taking long.   My firmware is 1.2. Is it normal because I see on Fiio's website that the last firmware is 1.1 ?

I listened to the E12 yesterday. It's powerfull enough to drive my DT880. But the sound with my cowon D2+ is not as good as Fiio X1 + E12. So I didn't buy anything, I will think about it a little more.   Thank you.

Thanks.   I'm going to test it in a shop tomorrow.

  Hi,   For ~100€, do you think I must go for a X1 or a E12 paired with my Cowon D2+ ?   I have a Beyerdynamic DT880 250Ω (my cowon can't handle it), a sennheiser PX100-II and Jays S-jays.   Later, I think I will sell the device (X1 or E12) and buy a X3II.

with GNU/linux support ?

Physical buttons FTW !   @Fiio : I'm ripping my entire CD collection in flac for this X3k (actually 121/211 CD done), don't let me wait too long. Give us some infos please. Official announcement of this X3k at 2015 International CES ?

OK, that's what I tought, but I'm not sure if it is a hardware or software limitation from X1. So I will wait for the X3k.

When connecting the X1 onto it, will it be able to use it as USB DAC ?

I don't know but I think it will be the same as the X3.

A X3K for January according to my dealer

Hi,   I bought a driver (~80€ with shipping) from showcomms (not available from beyer...) and I replaced it. It works perfectly now.

Hi,   I've made a test : I've put balance sound only to the left channel and put a piece of metal between right and left connections onto the left driver. Sound comes out normally on the right driver. So I think it's definitively not the cable (sad for my wallet I think).

Thanks for your reply. I've already checked the cable by testing continuity between jack and solder onto the drivers, and it seems to be OK.   It's weird because I don't carry my headphones, it still on my desk all the time.

Hi,   I've got the same problem with my DT 880 250Ω : I've got a very very weak sound in left driver. I've tried another source, same problem. I've tried to twist the jack, nothing. I've tested connections with a multimeter, it's OK. Nothing seems desoldered. I' ve got 236Ω between ground and...
