For manufacturers, 200GB = 200 * 1000 * 1000 * 1000 bytes = 200,000,000,000 bytes The card will have roughly this amount of bytes when you check its properties. However in the computer, 1024 bytes represent a 1KB. 200,000,000,000 bytes / 1024 / 1024 / 1024 = 186.26GB So it is normal for a...

I met with this problem recently. Just use a previous version of firmware (not Lurker's). Click Restore and not Upgrade.   See: http://www.head-fi.org/t/697035/dx90-2x-sabre-1st-page-downloads-info-inst-lurker0-fw-mod-link-1st-page-new-fw-2-2-0/12105#post_11546525   Also try taking...

      Works like a charm! Quoting for anyone who would find it useful.   From 2.2.0L0, used 2.1.5 with RKBatchTool and Restore (instead of upgrade). Successful downgrade to 2.1.5 After that copied 2.1.5L2 into internal storage, and did a Settings > Advanced > System Update. (Then do a...

Please help me.   I just upgraded to V2.2.0L0 (then did a factory reset as always recommended). And now I cannot downgrade it using RKBatchTool. Have already followed the steps on first page, installed the drivers, and the RockUSB device is installed correctly. (But then Device Manager...

  Yep, I was following that thread when I got the DX90, but haven't been reading up since I sold it. Oops.   I guess I shall wait for probably a few months to see how things progress?     I believe there is the DX90j? The version that is sold in Japan.   And there are also people...

Bumps for anyone in the same situation~

Was in need for some quick cash so I sold my beloved iBasso DX90 3 months ago. After some time of missing out on good quality audio, I decided to get Fiio X1. I even got a Fiio E11K to pair with it. Even though I still enjoy my music, I could not seem to derive the same enjoyment when I had...

I really appreciate this low cost budget DAP. The amount of work put in, the documentation, extra stickers, cable, silicone case... really, I feel Fiio X1 is really worth it. Just stating what hopefully can be improved :) Okay, shall use that for quieter scrolling! I have 1.3 installed and...

I prefer buttons that don't sound so audible though. I indeed use it in somewhere even quieter than library -- the bedroom. I organise my music in folders and some have close to hundred or more files, so it's yet even noisier to scroll and scroll. Guess I have to split them further. Just...

So after having X1 for a few days review: 1. Initially does not read one of my MicroSD. Gotta backup my music, then format the card using X1. Now the 64GB card is working well. 2. Scrolling is slow especially if you have a long folder of 100 plus songs. 3. Scrolling is noisy 4. Middle button is...

Alright thanks, I guess I shall convert those m4a to another format.

  Hmm.. It still can't play .m4a that are voice recordings from my Galaxy S4. It says "File not supported."

Okay oops, my bad. It's working good now :)

Just got Fiio X1.   Initial review: - Doesn't support one of my SDXC 64GB microsd where I have all my music - Can't even play .m4a files (had some recordings made from Samsung Galaxy S4) - Scrolling is a pain especially when you have hundreds of files   - Thought it's firmware problem...

  There's a README.txt in every version of firmware, and the instructions clearly stated how to upgrade the firmware. It seems like you didn't open them.

Hi, sorry for the noob question.   I installed Rockbox, and I am able to detect my microsd card on Mango. However, I could not find my files on the microsd on Rockbox?

Thanks for the nice suggestions cel. Between the two I would also probably go with that 1 ft KabelDirekt, nice length for my needs.

Okay, no problem. It sounds really good to me, so I think a good cable might give it full potential.

Yeah, it's the same cost vs enjoyment problem again.   I'm having the Bose Soundlink Mini :)

Thanks! I have two cheap cables and the same song sounded different on speaker when different cable was used.   So I'm looking out for cables to hopefully improve my enjoyment, so I'm free to all suggestions. Hmm.. audiophile grade cables like some silver cables or OFC (oxygen-free cables?)

Bought a portable speaker. Wanna buy a great quality 3.5mm to 3.5mm cable.   Would like to do something simple like this: Laptop -> cable -> speaker Audio player -> cable -> speaker   Saw this one on Amazon. Looking for even better options before I order anything...

Since you can access both, do a blind test. Ask your friend to play several songs on both players alternatively, without you knowing which player the song is playing from. State your preferences and let your friend record it down. If you happen to consistently like the 'sound experience' from...

Thanks :)

Hi all, can someone please do a DX90 summary of all the updates and firmware links?   It's a pain to go through so many posts just to find the new firmware link, and whatever new updates.   Also I wonder why are all these news in this thread instead of the iBasso website? Can't even find the...

I have loud constant hissing background too.   Anyway thanks for the song, nice vocals!
