Last release I removed Mango OS due to using native DX220 as base ROM. This time I tried to port DX220 ROM version 1.11.140 using DX200 as base ROM with new technique that seems to be more stable with original Mango OS intact. 🙂

–Yalp Store is added as Play Store’s alternative (I still keep Google services for those who want to install Play Store through other means)

-Revamped MangoPlayer UI with improved user experience

-Audio engine optimized for only audio playback (EQ/Gaplass features work)

iBasso DX220 Tidal Master Patch V2 for ROM V1.10.123 released!

 in News

 

 

Version 2 is updated for better reliability for some cases with occasional dropouts.

 

After iBasso releasing ROM update version 1.10.123 for DX220 device, some people reported issues about playback instability on Tidal with MQA files in Tidal Master. The symptoms can happen from occasional dropouts during screen off to severe level.

I made some changes in boot configuration which should lessen the burden that cause negative effects with Tidal Master tracks. It may not be 100% fix but should improve the reliability of Tidal Master playback significantly.

If you use Tidal application with MQA and have issues, you may try this firmware patch and see if it can resolve the those issues and happy listening. 🙂

Fidelizer on Windows 10 v1903 (May 2019 Update) and v1809 (October 2018) Update Report

 in Article

Hello everyone. I’ve finally updated to Windows 10 v1903 and I have high expectations for this update because it shares the same kernel base 19H1 as Windows Server 2019 which sounds really really good. I also forgot to update v1809 too due to being so busy at that time so here we go!

First, I’ll start with October 2018 Update. As l highly praised Spring Creators Update (v1803) being back to good sounding one again, this October 2018 quickly fell behind to the point I consider it worse than Creators Update. Though v1809 still some what more neutral tonal balance, its performance was rather disappointing.

Bass in v1809 is a bit veiled  and blurred with some sort of distortion. Midrange isn’t as expanding as previous v1803 and sound a bit thinner too. I wouldn’t say this degradation is as worse as from v1703 to v1709 as this is still some what acceptable and still considered better than v1703.

Now that v1903 is out, the first improvement I noticed was it’s much smoother and I can perceive much more micro detail. Bass is more vivid and deep with great clarity as I used to hear when Windows 10 first released before. Midrange is fuller and more expanded though it’s little thinner than v1507-1511. Treble is very crispy with fine details, it might be the best Windows 10 in this regard alone so far.

Though I still prefer more solid dynamics in Threshold line a little bit more but this 19H1 base really comes close and may have finer details to make up so I’ll put both v1511 and v1903 on second rank together.

  1. Threshold (v1507) – By very small margin
  2. Threshold 2 (v1511) / May 2019 Update (v1903)
  3. Spring Creators Update (v1803)
  4. October 2018 Update (v1809)
  5. Creators Update (v1703)
  6. Fall Creators Update (v1709)
  7. Anniversary Edition (v1607)

This is the best update after Threshold line for sure. I highly recommend every audiophile to apply this Windows 10 whenever possible and don’t forget to re-apply Fidelizer Pro optimizations after major Windows Update to make sure Fidelizer is running with 100% optimizations. 🙂

For new users, please read about PerfectDynamics 2.0 Sound Optimizations first for new improvements with Fidelizer ROMs.

 

After first successful proper iBasso DX220 ROM port to DX200 device, I tried to find how to make Mango OS usable but it seems to be impossible and I can’t bring DX200 Mango OS back to DX220 partition image.

As a result, I decided to remove Mango OS mode completely to avoid confusion. If you prefer Mango OS too, I recommend official 1.0.6 ROM with DX220 MangoPlayer too.
