For classical music and jazz V6 Classic is great. In that case strong subbas isn't needed and V6 Classic still has deep midbass and doesn't sound thin. It's warmer, more natural than Basic or Vivid. With Ether 1.1 oraz Audeze LCD-2 midrange sounds terrific with V6 Classic - trumpets, saxophones...

In my opinion Basic is a little more bass-prominent than Vivid and fuller in bass than Classic. It's because Vivid is more linear and stronger in presence region, but it's still deep and punchy in bass region. I find V6 Classic to be a little bit rolled off in subbas and high tones in comparison...

I'm impressed with Play's sound quality, especially with V6 Vivid op-amps. It's neutral, but precise, with deep bass, airy highs and clean and resolving midrange. I also enjoy the wide soundstage with V6 Vivid. I had a chance to check also V6 Classic and Basic configurations. I prefer V6 Vivid...

After removing mango interface and audio driver I reinstalled driver using setup file. This time it went good, I didn't have to install it manually. Listening about 25 minutes right now without BSOD :)   Edit: Too soon...

I've got Blue Screen too on Win 7 64 bit. After few minutes of listening :(

  Thanks! Looks like everything is fine. The newest versions are faster than before. Prior to 0.3.0 my DX90 was kinda lazy.   Button combination needs a little practice, got to be done fast, but works and is useful.

Everything is back to normal. Thank you very much for your work.

Same here, doesn't matter which language I choose. "Now playing" shows also name of current theme - "base skin", near track number. I'm using standard theme.   Also menus names are different than before, few new strange options showed up in main menu, like "recursively insert directories"...

  Thanks, I'll try that.

Does anyone experiencing a short pause after playing music? It's happening from time to time, no matter the source - built in memory or microSD card, no matter which FW version.

  I'll do the same or even I will ask about "new" version of 2.0.5 with 2.0.0 sound libraries - maybe it will be faster than waiting for new FW. I hope so.

Unfortunately all you're right about SQ changes. Damn it, iBasso. On 2.0.5 dynamics are gone, soundstage is wider, but depth sucks (the 3D like presentation is gone), also sound is warmer, there is less treble and sound is just boring and slow. DX90 with 2.0.5 reminds mi of DX50. I also got...

  Thanks, I was just about to paste it :)

  Maybe you should try flashing it with RKbatchtool, I think it should work. Someone posted link to "DX90 Tools" few post earlier.

  It works well with Windows 8, so I presume with 8.1 won't be a problem.

2.0.5 changelog:   Improvements with this firmware: 1. The slight lag of the control buttons' response, has been eliminated. 2, Missed last 2 seconds of songs rectified. 3. Touch screen sensitivity has been adjusted. 4, Improved read speed for exFAT formatted SD cards. 5, Optional digital...

So there is new FW - great! No... I'm afraid of changes.

Quote:   Nope. It's just USB DAC function driver, not new FW :)   Volume control works while using USB DAC, but there is no option to change to storage or charging while using DAC like in Astell&Kern's DAPs.

Works on Windows 8 32 bit using Foobar, but there is fade in effect and one second skip after playing song...

  You can try rkbatchtool which was linked by howdy few posts up: http://www.ibasso.com/download/RKbatchtool_for_DX50.zip   Manual is in the package - you can reinstall this way both firmware and recovery at once just by using 1.2.8 FW's image.

  It was done right with no effect then.   But... now my DX50 works. It's odd and funny. I left it for about two days, few moments earlier I gave it to my girlfriend joking, asking her to fix it. She turned it on, and it works :D Have no idea how it's possible.   1.2.8 soft was slow and...
