Here’s another feedback today. This time it’s from Fidelizer 8 Plus customer.

The only thing better than your customer service, is the improvements you get in sound quality. It’s always great re-listening to my whole music collection whenever there’s an update!

v 8.0 sounds smoother and more open. Very enjoyable, thanks

When audio system gets better for real, audiophiles can’t help but re-listening to whole music collection again. I’m happy to hear Fidelizer helps his system to that extent and happy listening. 🙂

Fidelizer 8.1 released – First update with many fixes and improvements together with 2,900th license purchase offer

 in News

 

Fidelizer Pro

 

I hoped to release version 8.1 before Valentine’s day but there were more cases to be resolved related to security having a few internal changes until it’s more stable enough.

While fixing reported issues one by one, I also was flooded with over 100 mails per day in during the first week of Fidelizer 8 release so fixing every reported issues took me longer than expected but it’s finally done now.

New features such as Core Isolation policy and execution with music player application are working properly now. I also found core affinity optimization didn’t work properly with new algorithm so I fixed that too.

I also improved permanent optimizations in Fidelizer Pro with rounding technique. Fidelizer Pro analyzes RAM calibration with 250MB block. If system detects 3.93GB with 64MB for VGA, RAM calibration will apply optimizations as 3.75GB.

With nearly 200MB miscalculated, audio tasks won’t perform according to ideal optimizations with tonal shift. By adding rounding technique with 125MB threshold, 3.93GB RAM will be treated as 4.0GB which is closer to ideal case.

Nimitra Computer Audio Server receives Stereophile’s Class B Recommended Components 2018

 in News

 

Stereophile's Recommended Components: 2018 Edition

 

Last year Nimitra was included in Stereophile’s Class B Recommended Components: Fall 2017 which is a huge landmark for Fidelizer products. It’s amazing to see Stereophile staff contacting small company reviewing their first product and get Class B in its first year.

Stereophile published Recommended Components: 2018 Edition on 15th March 2018 and Nimitra is also included in 2018 list as Class B Media Player. I’m really thankful to Mr. Kal Rubinson and Mr. Steven Plaskin for their support and their advice.

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)

They earned my respect not only for reviewing products for niche interests but also for their professional support and services while reviewing products too. After receiving so much support, I decided to return the favor by advertising in Stereophile and AudioStream starting in April 2018. 🙂

Modification updates in Fidelizer Mod products for Fiio X5iii and Chord Hugo TT

 in News

 

Chord Products

 

Fiio is odexed ROM and support ART runtime so I deodexed the ROM to make best uses of ART runtime improve transparency and imaging. However, stock buffer stage opamp are tuned for odexed file making sound too bright in some systems.

It’s not Fiio’s fault with their choice of buffer stage opamp doesn’t have sound signature matching with deodexed ROM. To resolve this case of incompatibility, I adjusted Fidelizer Mod level to upgrade opamps first in Reference and capacitors in Signature level.

I also made some adjustments to Chord TT product. Chord Hugo TT is more like battery powered home component so replacing 3.5 with 2.5 won’t be necessary so I chose to apply internal damping tweaks to improve device’s performance instead.

These changes won’t affect any client who applied FIdelizer Mod for Fiio X5iii before so they won’t need to send device back for adjustments. I’ll release non-deodex ROM updates for Fiio devices shortly later.

Added Chord Hugo/Hugo 2/Hugo TT into Fidelizer Mod products

 in News

 

Chord Products

 

After modding Chord Mojo for a while, I also receive inquiries to modify Chord Hugo and Hugo TT too. After accepting some works in Thailand, now I’m sure I can make Chord Hugo and Hugo TT sounding better for everyone with satisfying improvements.

 

Chord Mojo

Reference – The reason why Chord Mojo has powerful sound yet a bit veiled is because it can push 720mW at 8 ohm load but I’m not sure if resistors can really handle at full load so I upgraded 6 output resistors with 1% tolerance, 750mW output and 2 highend grade capacitors used in DX200.

Signature – I upgraded 2 input capacitors for USB charging and battery then tap battery directly to Mojo circuit board with high purity copper for full sound dynamics. I also replaced additional headphone jack with 2.5 termination using best silver-plated contacts.

I wish I could make Ultimate modification with Chord Mojo but I couldn’t find clock module worth upgrading from stock ones yet. Also, for about $300 modification cost for Signature level mod is surprisingly great enough for me to feel satisfied with decent DSD tracks from David Elias.

-Upgrade 6 output resistor with 1% tolerance and 750mW output for uncapped performance at 8 ohm load
-Upgrade 2 output capacitor with the same highend grade ones used in DX200’s Fidelizer Ultimate Mod
-Upgrade 2 input capacitor for charging and battery with best ones for solid sound performance
-Modify battery module to use direct connection with high purity copper wiring for full sound dynamics
-Replace additional output jack for 2.5 termination with silver-plated contact for balanced ground topology design

 

Chord Hugo / Hugo 2

Reference – The reason why Chord Hugo sounds harsh and unforgiving was due to stock capacitors implemented for best specifications in budget. Upgrading capacitors will resolve this harshness and improve musicality a lot.

Signature – Chord Hugo use dual mono battery design so tapping battery to Hugo circuit board directly will require amount of work. I also replaced additional headphone jack with 2.5 termination using best silver-plated contacts.

I never liked Chord Hugo when it came out and I was little reluctant to accept modding Chord Hugo unit from DX200 with Fidelizer Ultimate Mod customer. After listening to modified Chord Hugo, I was truly blown away beyond expectations.

-Upgrade tantalum capacitor with highend grade ones fixing harshness sound signature
-Upgrade aluminum capacitor for charging and output stage for solid sound performance
-Modify battery module to use direct connection with high purity copper wiring for full sound dynamics
-Replace additional output jack for 2.5 termination with silver-plated contact for balanced ground topology design

 

Chord Hugo TT

Reference – Stock unit already sound decent but signal wire to output circuit board can be improved for much better audio performance. I also upgraded aluminum capacitors in main circuit board a bit.

Signature – Tantalum capacitor in Hugo TT doesn’t produce harshness like Hugo so I put this upgrade in Signature level for further improvements. I also applied some internal damping in unit to reduce interference making more analogue sound.

As Chord Hugo TT is very heavy, I need to factor additional shipping cost for each level too. Output capacitors are fine grade already so upgrading on this part should come after other mods in Ultimate level.

As you can see from picture that I upgraded other internal cables and opamps are upgraded too. I thought about adding them into Ultimate level but I should leave those as optional customizable options.

-Applied internal damping in main unit to reduce interference making more analogue sound
-Upgrade tantalum capacitor with highend grade ones improving transparency and imaging
-Upgrade aluminum capacitor for charging and output stage for solid sound performance
-Upgrade signal wire to output circuit board for fuller dynamics and musicality

 

Since these new products cost me about the same so I’ll change Chord Mojo to Chord Products with product model options. I’ll add more Fidelizer Mod products based on my past works and and finalize its design for Portable Products soon. 🙂
