Added Fiio M15 with Fidelizer Ultimate Mod feedback from Damien

Fiio - M15 Ultimate Mod

 

Here’s a new feedback today. He shared his feedback after receiving Fiio M15 with Fidelizer Ultimate Mod for about 2 weeks.

It’s taken a few days to settle/burn in but now, it’s sounding great! Quite high resolution and ‘speed’ but lovely tone, and musical timing. Obviously I can’t compare with the unmodded M15, but it’s streets ahead of my old M11 (as it should be!).

Thanks!
Damien

Fiio M15 is the hardest DAP to crack for modification. I’m glad to hear this ultimate project went well without issues. It’s tuned to be highly resolving with great musicality. 🙂

Fidelizer 8.6 released – Some more fixes and improvements with Windows 10 v2004 update

 in News

 

Fidelizer Pro

 

Some people asked since few months ago if Fidelizer development is still active and yes it is. I have some internal updates over time and don’t save features and optimizations to prolong version releases.

Now version 8.6 is ready with some changes and optimizations applied. I waited until Windows 10 with 20H1 update released first to confirm further changes and launch it with some bug fixes improvements.

Recently I have a client using Sonarworks as DSP sound card so I also added Sonarworks apps to be recognized as audio processes too. I also added option to preserve current Processor Priority Policy as requested. 🙂

 

Changelog for version 8.6

-Fixed fidelizer.key data generation bug on some new cases

Here’s another feedback today. He shared his feedback after using new Fidelizer for about 2 weeks.

Hi Keetakawee,

I could perceive that Fidelizer brought a very nice and welcome improvement of sound quality in addition to JPlay and Audiophile Optimizer. The playback is smoother, more detailed and more natural. Thank you very much!

Heiko

I’m glad to hear how Fidelizer Pro is working fine with JPLAY and AudiophileOptimizer today and happy listening. 🙂

Here’s a new feedback today. He shared his feedback after receiving new Fidelizer update today.

Hi Keetakawee,

That was it, fixed and reloaded everything and it works perfectly with correct version number. I would like to thank you Keetakawee for producing such a fantastic product, the sound I am currently enjoying in my system is fabulous, the most beautiful part is that a digital recording is no longer a flat dimensionless image it’s this immense three dimensional volume that has front to back depth and side to side width and top to bottom height extending beyond the speakers. The sound emenates from a volume it’s just incredible much thanks! For once digital is vible reproduction of a recording. There are more things things than I can mention that your product corrects/ improves!

Thanks again
Harry

I’m happy to hear Fidelizer helps improving stereo image and depth bringing more life to his system and happy listening. 🙂
