Added X7ii Advanced ROM feedback from Eduard-Catalin Tudor

 

Fidelizer Mod

 

Here’s another feedback today. I received feedback for both Fidelizer Pro and Fiio X7ii so I’d like to share them both at the same time.

Purist ROM Advance upgrade is worth every penny. It reveals more details, a more natural timbre, realistic tempo and stage. Both Fidelizer versions, ROM and PC are probably the best and and probably the last improvements I had to consider for the ultimate SQ I might need. I’m really happy with what I got for such a reasonable price. Again, I feel the need to send you beer … Cheers

I’m happy to hear Fidelizer products making a reasonable upgrade for you and thank you for supporting Fidelizer and your extra tips for beers too. 🙂

Added testimonial from Eduard-Catalin Tudor

Here’s a new feedback today. It’s been a long while since last feedback due to being occupied with many things to do at the moment.

Even Chord Qutest is a gorgeous DAC, with Fidelizer Pro on my PC it sounds much, much natural. Even my cat feels the change. Again I have to express my gratitude, deep appreciation and respect for your great work.

As a fellow cat lover person, I’d like to recommend checking this cat’s response with my system. 🙂

Fiio X5iii Purist ROM version 1.2.1 released – Bright sound signature is now fixed with as Odexed ROM

 

Fidelizer Mod

 

Sorry for the long delay. I was visiting my parents since last month and I didn’t bring my ROM cooking materials with me. I only got back to my place few days ago and started cooking new Fiio ROMs as soon as possible.

As some people reported and mentioned in forums about Purist ROM sounding brighter than stock ROM, it was caused by de-odexing ROM which is a common practice for ROM cooking with ART runtime.

Odexed file is compiled as Dalvik byte code so app will run through Dalvik VM. De-odexing ROM will allow ART runtime to run app natively which also improve transparency and resolution in audio too.

However, opamps used in Fiio devices tend to sound brighter so de-odexing will make those characteristics more revealing too. I will publish odexed ROM so it won’t change sound signature on stock unit and use de-odexed ROM for Fidelizer Mod version.

Nimitra Computer Audio Server and Nikola Linear Power Supply receives inearspace’s Pride of Place Award

 

inearspace's Pride of Place award for Fidelizer Nimitra Computer Audio Server and Nikola Linear Power Supply

 

This review was actually published in last month for both  Nimitra Computer Audio Server and Nikola Linear Power Supply. However, I was overloaded with orders to finish before attending the show so I couldn’t publish it right away. I’ll start publishing feedback received too.

This is probably the first serious review for Nimitra and Nikola in headphone systems so I hope this will be a good reference for headphone users to consider using Nimitra and Nikola with headphone setup.

Fidelizer Nimitra: inearspace's Price of Place

The Nimitra is none of the things that the iMac is. It is not loud nor brash and seems to have a controlled fluidity to it. Keetakawee made a big statement when he went along and said that this was an a server for analogue lovers but I think he may just be onto something here. Obviously the rest of my system is helping achieve such an analogue sound, the R-2R arrangement in my d1-seven certainly helps, as does that lusciously tuned Audeze LCD-MX4 but there is an apparent glare with the same system running off the mac, and noticeable artifacts all through the sound and they just aren’t there with the Nimitra, instead the background is dead quiet. The best part is this is all the quiet before the storm, it starts controlled, quiet and smooth but then you realize the intense dynamism that this is capable of, something that really comes out with Jack White’s new LP “Boarding House Reach”. While the Linux based BMC PureMedia wasn’t as distorted or lively as the iMac, it didn’t ever provide that crunch, that power and that is where the Fidelizer really moves things on a gear. It makes the BMC sound sterile and boring yet it is as refined, it has better emotion and realism, aided by a firmer (but no more present bass) and more agile and snappy treble.

I’m happy to hear Mr. Sonny Trigg loves Nimitra enough to give Nimitra the first “Pride of Place” award in server category. You can read full article about Price of Place Award and see other cool products and don’t forget to check his Nimitra and Nikola review too. 🙂

iBasso DX200 Purist ROM version 2.9.209 released!

 

DX200 - Purist ROM

 

I thought I’d release DX200 2.9 ROM together with PerfectDynamics 2.0 but sadly I haven’t finished it yet especially after listening to classical concert in Golden Hall. There’s a lot for me to do to improve Purist ROM for 2.0 release.

However, I managed to fix a few issues during development so I’ll also include those fixes into this release too. I apologize for the issues that happened with some cases in Enhanced / Advanced ROM and now they’re all resolved. 🙂
