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.

What’s inside the Network Player?

Interior of Teac NT503

Since yesterday’s question in Facebook about USB and Ethernet audio, I found some people are interested in learning about how Network Player works inside. I’m going to use most recent yet affordable product Teac NT503 as a model to explain. Top left is Ethernet board and top middle is USB board.

As you can see, this network board is very big, much bigger than USB board. It has a lot of chips like CPU and controllers inside.  Yes, the network board is actually a mini PC board that receives data from network and sends from built-in audio interface to digital receiver board.

If you connect DLNA Renderer PC to USB DAC and stream music from your phone, it will work exactly like that network board but use large board USB audio interface instead of tiny chip in network board. So building a dedicated computer transport outside should have more room for improvements.
