I understand SACD and CD ISOs.

Thanks for the update, iBasso.

Many thanks for the firm Ibasso.

  Great news. Many thanks Ibasso.

  Try to download the last version again and reinstall the drivers. The last version doesn't have problem with the certificate, I am using Windows 8.1 and this problem doesn't happen.   And Tidal doesn't recognize the DAC because the drivers don't work correctly.

  Yes, rockbox supports replaygain.

  In my case, using Linux, by the moment I made the update without problems.

    Amazing. 

  Congrulations.   I can't help you with the other topic. :)

  There Is not cue sheet and they are ripped from CD.

I think I  detected a bug in RB. When I play X - Ed Sheraan in FLAC format, RB plays only the first 10 seconds of each song.    However it plays without problem in Mango from the same SD card. 

  I also perceived a lower volume but it is with replaygain active and files with this tag. It is the same case, Rockbox have an option to up the volume automatically for those files.

  The rockbox is in another file, you can download the last version from: http://napych.com/other/rockbox-for-ibasso-dx90/official-rockbox-binary-builds/ Or this post: http://www.head-fi.org/t/727669/rockbox-for-ibasso-dx90-dual-boot-with-mango-stock-firmware/795#post_11534257

  I used it and it works without problem.   You have to copy the .rockbox to root of internal memory and copy the update.img to same place. Then you select Settings -> Advanced Settings -> Firmware update.   It installs the firm and after the reboot, if you place hold on appears a screen to...

  Many thanks, it worked without problems.   I deleted apps and rocbox folders and copied .rockbox.

  Finally, I got to install FW 2.2.0 + Lurker's L0 + RB Loader, first I followed the instructions from the first page and then I installed this firm. However, I am able to boot Mango but when I try to boot Rockbox it shows an error: Rockbox installation missing.   How can I make to have...

  Someone tried it? I tried to install it from SD but the recovery shows firmware not recognized. 

  +1

  Thanks.

Which is the best version of Rockbox?   Headwhacker or rockbox git.

  Does Pono Music sell Europe? I think they are a US service only.

  I rip my CDs in FLAC or OGG, I use soundkonverter ( I use Linux).   If there is a new album and the HD version is near in price to CD, I bought it, if not CD.  Althought I buy little in HDtracks, I live in Europe and the most of times I obtain the message: "This product is not currently...

  Rading this posts, I should be very singular person.   I love my Shure 535LTD with DX90.

  You can use the DX90 like a DAC connected to a USB port of the PC.   You have to install the drivers and configure the output of the player to use the DX90.

  Hi.   I have a question about DX90.   The DX90 support DSF files. Is it able to play native or it converts DSF files to PCM?   Thanks.
