Introducing Lira, the flagship network station as successor of EtherStream2 and Nikola2

 in News

 

Lira - Side

 

On Christmas night in year 2024, I had a dinner with my audiophile friend who purchased EtherStream2 network switch and Nikola2 linear power supply to upgrade from previous highend network switch and use with his dCS Vivaldi One streaming CD player.

After dining, he proposed the idea of building a better version of network switch knowing what I’m capable of from listening to Erawan flagship streamer product in his system. I confessed to him that I considered it but it’d create a dilemma with EtherStream2 + Nikola2 combo.

 

Lira - Back

 

He understood my point and clarified the issues he had further. The switch is so small. It’s very hard to keep switch attached with isolation feet after swapping audiophile ethernet cables. Cables from Nikola2 to EtherStream2 + AirStream2 + main router are cluttering audio rack too.

At that moment, I realized that making linear power supply infrastructure and route access to network as a single box product that surpasses both EtherStream2 and Nikola2 is the solution we’re looking for. Customers can send EtherStream2 and Nikola2 to be upgraded as well.

 

Lira - Internal

 

With a clear vision in mind, I finalized Lira as a suitable companion of Erawan flagship streamer. Aside from thick aluminum chassis enclosure and footer to handle resonance and vibration control better, Lira has the improvements over EtherStream2 and Nikola2 as below:

 

Improvements from EtherStream2 network switch
-Bypass power switch and input socket completely improving purity of power distribution
-Optimized output for shortest path possible to supply power from output board to network switch circuit
-Upgrade input capacitor upgraded with high quality polymer hybrid design with much lower impedance
-Upgrade noise reduction capacitors with even lower ESR with improving tuning for lower impedance and current leakage
-Upgrade resistors around grounding and internal circuit components to further reduce noise in circuit

 

Improvements from Nikola2 linear power supply
-Add dedicated chassis ground connector to ground conditioner product
-Change output connector to gold plated XLR with very high voltage rating (same termination as HDPlex)
-Upgrade DC output cable with high quality pure copper wiring
-Upgrade diodes with Schottky design with years of listening tests with different models
-Upgrade internal wiring with high quality solid core pure copper wiring
-Upgrade output transformer with 100VA Toroidy audio grade transformer
-Upgrade stock fuse with improved dynamics and musicality

 

Lira - Front

 

After testing Lira in a few audio shows and with highend to ultra high-end level systems using $30-50k sources from CD and vinyl as reference, I’m confident that Lira will deliver worthwhile improvements that meets ultra high-end standards.

The product price will be $1899 USD with 30-day money back guaranteed and free shipping until 30st November 2025. You can read more about Lira network station product in details before ordering with discount up to $900 USD if you upgrade from EtherStream2 and Nikola2.

Introducing HyperLink, the world’s most affordable audiophile network switch

 in News

 

HyperLink - Network Switch (Front)

 

Today Fidelizer is launching HyperLink, the world’s most affordable audiophile network switch at only $169 USD! We have been designing products to improve streaming experience for over 7 years and we can finally developed product with best price/performance as below:

 

  1. Accept 12VDC input – Most affordable network switches with 5VDC input can’t share power source with other Fidelizer products
  2. Full scale dynamics – Most network switches we tested before often lack full sound experience, probably due to 5VDC input
  3. Isolation transformer support – Network switch with isolation transformer design can reduce interference from connected devices
  4. Good circuit design for modification – Good network switch should have multi-stage power regulation with radical can capacitors to upgrade

 

To find network switch that checks all these boxes at very affordable price point is very hard. We actually found one by coincidence while looking for parts to build Aura medical grade power supply that supplier also sell network switch too.

After finding the right network switch that aligns with our design philosophy, we applied the following modification as below:

 

-Upgrade input capacitor upgraded with high quality polymer hybrid design with higher capacitance and much lower impedance
-Upgrade crystal clock with higher precision clock module
-Upgrade capacitors in power supply section with higher capacitance and lower impedance
-Remove low quality solder in power input socket and replace with high quality solder to improve dynamics and transparency
-Components are soldered with high quality solder providing solid bass and dynamics
-Install high quality 3M rubber feet for better vibration control

At fraction of EtherStream’s price, HyperLink can deliver promising results in high-end audio systems. We recommend using HyperLink network switch together with Aura medical grade power supply. Aura can power 12V WiFi router before HyperLink also.

The product price will be $169 USD with 30-day money back guaranteed and free shipping until 30st April 2025. You can read more about HyperLink network switch product in details before ordering and happy listening.

Introducing EtherStream+ Upgrade program for original EtherStream customers

 in News

 

EtherStream2 - Network Switch

 

After successful launch of EtherStream2 network switch, I received a lot of positive impressions from clients and a few of them also own original EtherStream unit with satisfying improvement from previous version.

However, there are over 300 units of original EtherStream sold before launching EtherStream2 network switch and I don’t want early adopters who’s been supporting Fidelizer products using an obsolete product.

Just like Nimitra, we’re offering EtherStream+ upgrade program with the following changes to make original EtherStream performing at the same level of EtherStream2 with new technologies as below.

 

-Upgraded clock module with more suitable specifications for networked audio improving musicality
-Upgraded capacitors with new tuned value and have better specifications for lower impedance and current leakage
-Upgraded output transformer with high quality EMI/RFI reduction and vibration control sheet for router

 

It’s almost like modifying original EtherStream all over again except resistor part so the whole process will be $179 USD plus shipping. You can ship original EtherStream unit after confirming product and serial number to get your unit upgraded to EtherStream+ version.

I can assure you that these new found improvements will be worth every penny as EtherStream2 + Nikola2 combo can replace a few $3-5k network switches based on clients’ feedback I received and witnessed myself. EtherStream+ will also deliver that level of performance too.

If you’re interested in upgrading your original EtherStream product to EtherStream+ version, feel free to check EtherStream2 product page and purchase EtherStream+ Upgrade option to start EtherStream+ Upgrade program and happy listening. 🙂

EtherStream Network Switch receives Positive Feedback Writers’ Choice 2020 Award

Positive Feedback Writers' Choice Award 2020 for Fidelizer EtherStream Network Switch

 

Last year I launched EtherStream Network Switch due to some unforeseen events as originally personal mod being appreciated by Nimitra clients. It was a really pleasant surprise that modified switch was sold for almost 200 units now.

Last week I received an email notification about EtherStream receiving Positive Feedback Writers’ Choice Award. More than getting the first reward for EtherStream, I’m happy to see audiophiles are taking network improvements seriously in this year.

Elimination of noise from your playback really helps you sit up and listen closely to the music! With optical streaming, I really thought I was about as close as I could possibly get to the musical truth, but with the EtherStream—the overall sound quality is shockingly close. In fact, so much so, that all of my recent thoughts with regards to going all optical have now completely changed—the EtherStream is giving me probably 95 percent (or better) of the clarity and transparency that I was getting through the optical experience. Seriously, it’s virtually a wash! When compared to the NetGear switch that typically resides in my system, the EtherStream delivers a sound that’s not only deathly quiet, but punchier in character, with deeper, more defined bass and a significantly more liquid midrange. Fidelizer has done it again, and the EtherStream is very highly recommended!

This year Covid-19 hits hard on everyone. I hope you guys will remain safe with your family and enjoy the music during quarantine. You can read full article about Positive Feedback Writers’ Choice 2020 Awards and see other cool products too.

And don’t forget to check out the first and the second review of EtherStream Network Switch product. It may sound a bit weird to have two reviews but you can learn more from both perspectives from different systems. 🙂

EtherStream Network Switch review on HiFi Knights by Dawid Grzyb

 in Review

 

EtherStream - Main

Actually, this review was published for a while but I’ve been so busy with delivering EtherStream Network Switch and many other products so I forgot to publish this until now. I’m so sorry and also very thankful for you guys’ continuous support.

This review is written by Dawid Grzyb and is the first Fidelizer product review in HiFi Knights. It’s thoroughly investigated review with every nook inside examined and shown. Not that I mind since I also showed and explained what I did for personal use.

I like how he compare EtherStream to his reference USB reclocker and galvanic isolation components and see that he can find similar improvements on network at more affordable approach as below.

Positive Feedback

The micro iUSB3.0 reclocker and EtherStream were quite alike voiced to my ears. The former’s action was more audible, but as previously not by a lot. Once again I thought that better LAN cables could even things out a fair bit, but today’s skirmishes with my USB boxes weren’t important per se as one doesn’t replace the other. Their action stacks. These investigations were conducted mainly to ease my own curiosity, but also to find out whether Keetakawee’s box could keep up with two fine examples of iFi audio’s USB engineering and remain just as relevant elsewhere. If today’s put up against USB sorters strikes you as odd, all fundamentally shave excess noise and make music more liquid, that’s their common ground. That’s why the main disparity was in their different junctures of my setup, not audible job. Even handicapped by stock LAN cables and away from streaming services, Fidelizer’s deck held its ground very well all things considered. What this switch was able to accomplish in my room, was already not too shabby for its coin and sub-optimal conditions. Something tells me that supported by better LAN cables, PSU, and used with streaming services, it would go faster, bigger and bolder, but that’s a story for another time. What’s important now is EtherStream’s audibly potent and beneficial input, with no strings attached. Yes, please.

I didn’t send switch with Nikola linear power supply so reviewer can review network switch on its own merits but you can upgrade linear power supply for better sound quality too. You can read his full review and see his journey about network improvements for more details.
