Introducing NikolaS (Signature Upgrade) as premium upgrade version at $695 USD

 in News

 

NikolaS

 

Hello everyone. After NimitraS being reviewed in StereoNET UK, Marc is also reviewing NimitraS with new linear power supply for StereoNET Australia review right now. It’s called NikolaS for Signature upgrade to match with NimitraS I released earlier.

As I built custom version of Nimitra, I also built custom version of Nikola too since its release. Sometimes we tried new designs with improved components or even new circuit design for clients. Sometimes I also built over $1,000 version of Nikola too.

But making an official product is different, you need to make sure it’s mature enough to stay like that for everyone with good reference, good reliability and selected parts won’t be changed after it hits production line.

Based on feedback I received with Nikola and its custom version, I can finalize the design plan for NikolaS as official product and release now. It’ll be an ideal match for NimitraS with firmware 3.0 update producing most analogue sound server and it can greatly improve sound quality of DAC and other servers too.

After research and development for price / performance ratio, the final price for upgrade to NikolaS is $695 USD with the following features.

 

NikolaS (Signature Upgrade) Features:

-Capacitors are upgraded with improved matching set providing fuller dynamics and richer sound
-IEC inlet is upgraded with Furutech FI-03 Gold model improving details and resolution
-Internal wiring is upgraded with 14 AWG high purity pure copper tuned for analogue sound (Made in USA)

 

Nikola customers can send unit back to apply NikolaS upgrade at $200 more meaning there’s no upgrade fee to upgrade from Nikola to NikolaS. Fidelizer will provide free shipping during introductory period for all Nikola purchases in November 2018.

You can read more about Nikola Linear Power Supply product and order with optimal voltage your audio device according to our recommendation. We also changed USB option to be USB Host meaning you can use any USB cable to connect with Nikola 5V version. 🙂

Sorry. Did I scare you? Shortly after the announcement, I found a way to repack Purist ROM I modified. Oreo has a lot of security features added making ROM customization becoming harder but not far from possibilities.

 

-Based on firmware version Oreo 8.1 Beta 0.01.008
-Play Store added (Not working yet. I recommend Yalp Store for now)
-Apollo – Fidelity Edition from https://forum.xda-developers.com/android/apps-games/apollo-music-player-fidelity-edition-t3038629 included
-Revamped MangoPlayer UI with improved user experience
-build.prop tweaks for better video and storage performance and improve battery life
-Audio engine optimized for only audio playback (EQ/Gaplass features work)

 

Download: iBasso DX200 Oreo 8.1 Beta Purist ROM | XMOS Firmware 1.2 Update

 

Installation Guide

First of all, this Oreo ROM comes with Verity enabled to protect system partition images. Even if you managed to flash modified system image and boot properly, those files won’t be updated and use older files from cache partition. To disable Verity, please follow the instructions below.

1. Go to Settings > System > About tablet and tap “Build number” for 7 times to enable “Developer options”
2. Tap back arrow and enter “Developer options” and enable “USB debugging”, press OK
3. Download Disable Verity package and run disable_verity.bat file (You can install driver from Official Oreo ROM package)

After DX200 boots up properly with Verity disabled, you can start flashing Purist ROM now with these steps below.

1. Turn off DX200
2. Connect DX200 with USB connection to computer while holding play button switch
3. Install Rockchip USB driver included in update tool
4. Flash Official Oreo ROM Beta firmware from iBasso with instructions provided in update tool
5. After successfully flashing official one, flash Purist ROM again

 

This firmware is still in beta stage so it’s not stable yet. If you have any issue with Oreo ROM beta, you can always go back to official 2.1.94 version and then flash Fidelizer Purist ROM thereafter for better sound quality and system performance. 🙂

iBasso DX200 8.1 Oreo beta ROM impressions and Purist ROM possibilities

 in News

EDIT: Well, I released Purist ROM for iBasso DX200 with Oreo update now. 🙂

 

Hi, everyone. Oreo beta ROM came out yesterday for iBasso DX200 and I spent all day and night testing and checking things out. So far sound quality seems to be promising though I’ll miss Purist ROM optimizations until preparations are ready for Oreo ROM.

Current Oreo ROM can support LDAC through developer options and force bluetooth detection option which is good. UI is more responsive in launcher but Mango is about the same. MangoOS seems to be better though. However, file access to storage is slower than 2.10.215 ROM.

I think I’ll port new files to 2.10.215 ROM to use for time being until they improve file access performance in next version. If you don’t change micro SD card and re-scan frequently, you may try using Oreo ROM for a while with bluetooth headphones.

As for ROM modding potentials, it doesn’t look good. I can repack and flash update.img safely but repacking system.img and vendor.img will freeze at logo screen. I tried many ROM cooking tools and bought few more that supports Oreo ROM but no luck yet.

Well, this isn’t the first time we have obstable as I reached out to iBasso and they released Factory image and flashing tool for me to build the world’s first DX200 custom ROM with Play Store and some optimizations to improve device performance so they may lower restrictions after it goes public.

For worst case scenario, I can still modify the ROM to some extent but it’ll have limitations with current situation. I’ll continue my research for Oreo ROM modification. I already informed iBasso about the situation and hope to hear back from them soon.
