Fidelizer Upgrade Program – 2,500th purchase offer including Purist ROMs

 in News

Fidelizer Pro

 

Now we’ve reached 2,500th milestone, half way to go for 3,000th license. As a reminder to inform customers that they receive refund for returning customer purchase, I’m running purchase offer again in this week.  I also sent partial refund back for customer who placed an order on 15th May 2017.

 

Fidelizer Plus: US $39.95 —> $34.95 (Expired)
Fidelizer Pro: US $69.95 —> $59.95 (Expired)
Fidelizer Enhanced ROM: US $49.95 —> $44.95 (Expired)
Fidelizer Advanced ROM: US $99.95 —> $89.95 (Expired)

 

This offer will last until 1st October 2017. Discount rate is the same as purchasing Fidelizer software again so new customer and returning customer will get the same price. You may order again anytime and receive partial-refund as discount later after this campaign is over.

Since I also introduced Fidelizer Purist ROM in Portable Products section recently, I think this should be a good opportunity to introduce purchase offer for Fidelizer Purist ROMs as well. I also added upgrading from Enhanced to Advanced ROM option today too.

I hope this will be good chance for you to consider upgrading Fidelizer software. I also made adjustments to have fidelizer.key filled automatically when you use “Order Fidelizer” button in Fidelizer software. I hope this will make order process easier. 🙂

Fiio X7ii added to Fidelizer Purist ROM repository with a quantum leap optimizations!

 in News

Portable Products

 

I’ve been receiving requests about Fiio X7ii Purist ROM for a while. As we learned past experience that first release will often come with bugs to be resolved so I waited until version 1.0.1 shipped out first then Purist ROM will follow and it’s finally here.

-Based on official Fiio X7ii 1.0.1 ROM
-Deodexed
-Apollo – Fidelity Edition from https://forum.xda-developers.com/android/apps-games/apollo-music-player-fidelity-edition-t3038629 included
-build.prop tweaks for better video and storage performance and improve battery life
-bundled audio effects removed but keep main engine (Poweramp works now)

Download: Fiio X7ii Purist ROM

 

Installation Guide

1. Download Factory Tool provided by Devin http://x7iipack.fiio.net/X7MKII_firmware_upgrade_tool-FW1.0.0.zip
2. Turn off Fiio X7ii
3. Connect X7ii with USB connection to computer while holding previous track button
4. Install RK USB driver included in Firmware Upgrade Tool and replace update.img image with mine.
5. Open X7II(Chinese text).exe and press the green button in middle right flash the ROM

 

I also added a quantum leap optimizations in Advanced ROM for the first time with Fiio X7ii releases. I’ll officially elaborate about these big improvements in details later. Please also check Portable Products for more details about ROM upgrades and hardware modification.

Nimitra Computer Audio Server receives Stereophile’s Class B Recommended Components Fall 2017

 in News, Review

Stereophile's Recommended Components: Fall 2017 Edition

Do you still remember the great excitement I shared here in July? Nimitra was reviewed by Stereophile in July and I thought that’d be the biggest achievement of the year. And today I’d like to share joyous event that Nimitra is now included in Stereophile’s Class B Recommended Components!

Nimitra is the first hardware product from Fidelizer, introduced in 2016 without so much of marketing. I told myself that some days Fidelizer products will be included in Stereophile’s Recommended Components but I never imagine to have Stereophile’s Class B product in first year.

I’m very thankful to Mr. Kal Rubinson who contacted me for reviewing Nimitra as multi-channel server in Stereophile right after seeing Mr. Steven Plaskin’s review in AudioStream. I’m so fortunate to receive so much support from passionate reviewers for all blessings I received in this year.

Fidelizer Nimitra Server: $1395
A fanless implementation of an Intel Celeron J1900 2GHz processor, the Nimitra is the first server from Thailand-based Fidelizer, who specialize in using Windows as a music-playback platform. Measuring only 8.9″ by 7.9″ by 1.7″ and supplied with an outboard power supply (a 12V brick; Fidelizer’s larger and reportedly better Nikola supply is a $495 option), the Nimitra is bundled with dBPoweramp’s Asset UPnP file access and the JPlay app for streaming output—and is, as KR reported, multichannel-compatible. Kal used the Fidelizer Nimitra with his miniDSP uDAC-8 multichannel processor—”setup was almost trivial,” he said—and found the combination “absolutely delightful,” and “easily the equal of” his Mac mini–based server: “Finally, a great-sounding and affordable multichannel server that works with USB or with HDMI!” (Vol.40 No.7 WWW)

I wish I could have provided better support during Nimitra review with exaSound e38. I’ve published testimonial from Nimitra customer using exaSound e38 for multi-channel audio. Thanks to experience I gained during review, I could support real customer better. 🙂

Fidelizer’s next year server

 in News

Nimitra server was introduced in TAV 2016 event in Thailand for the first time as an affordable highend server that worked its way to be reach Stereophile’s cover page in just a year. This accomplishment means a lot for products to be released in future.

I started receiving custom version of Nimitra server inquiries right after launching Nimitra and build a few custom units from time to time. This time is quite special with some unique features and has potentials for next year’s plan so I’d like to share the results before shipping today.

 

Fidelizer's Next Year Server - 1

Fidelizer's Next Year Server - 2

Fidelizer's Next Year Server - 3

 

This special custom server unit will be sent to our special guest who’s been patiently waiting for 3 months. I normally ship Nimitra and Nikola in 1-2 weeks but this boy needs a lot of research and development for new features so it is actually quite fast.

This is the first single box solution packed with a lot of new features. It’s quite a surprise that I found myself working on custom builds for customers wanting to afford more for better qualities and I’ll have my next custom server in car audio for the first time.

Fidelizer Mod’s inspection for Cowon Plenue 1

 in News

I’ve been modifying audio gear for clients in Thailand for many years as a hobby. I figured I should share my research in Fidelizer website from now on so I’ll start the first one with Cowon Plenue 1. I’ll write my past projects in future when I have time.

I received Cowon Plenue 1 from my client for about a month now. He said it sounds quite bland and narrow requiring EQ to make it Plenue more juicy. Now it’s time for Plenue 1 to shine after modifying a few DX200 and X5iii with Fidelizer Ultimate Mod.

 

Fidelizer Mod - Cowon Plenue 1

 

Cowon Plenue 1 has quite interesting digital audio implementation. It uses Burrbrown PCM1792A DAC chipset with Wolfson WM8998 audio hub for interface. Before we continue with analog stage implementation, let’s see how PCM1792A works.

 

 

As you can see, PCM1792A has balanced output configuration requiring I/V stage for output stage. From our inspection, we found 3 x OPA1612 op amp doing the following jobs.

2 x OPA1612: I/V and LPF stage
1 x OPA1612: Output and buffer stage

The I/V stage will have two small pot for each channel to adjust voltage output. I thought about calibrating voltage output too as I did before with FX-Audio DAC-X6 DAC but the board was put behind display panel so I can’t do measurements during operation, let alone listening.

So I decided to use different opamps with similar specifications from different models instead. Output and buffer stage can be replaced with more powerful ones but I’ll pick ones that won’t draw too much current and retain similar sound signature.

I also thought about upgrading capacitors too but it needs to be very thin so I’ll look around for a while and see if I can find better capacitors to upgrade. I’ll upgrade battery wiring with high quality ones that should keep Cowon sound signature with other internal tweaks.

I thought using dedicated audio hub WM8998 with separated clock will have potentials for upgrading clock modules inside but it doesn’t look like I can find any information about its frequency like I did on Oppo UDP-205 recently (Will post about that later).

I think I can modify Cowon Plenue 1 DAP up to Signature level if I can find any worthwhile parts for additional improvements. For Reference level, I think upgrading opamps alone would be suffice for important parts. He should be happy without having to keep changing EQ now.
