When I was exhibiting products in BAV audio show during 6-8 June 2025, I received a request from my friend’s store about building an affordable streamer as a Roon core. Although there’s also Nimitra Classic but most people prefer Nimitra2 as true contender.

After giving some thoughts and consulted with a few hifi specialists, we finalized the design for “CoreStream” streamer that can handle 300,000 songs in Roon library with can handle MUSE DSP efficiently. CoreStream also come with other streaming solutions similar to Nimitra too.

We built CoreStream with vision in mind to create the powerful Roon core while maintaining low power requirements and noise. We chose Intel N100 processor because it draws only 6W but can scale with high performance to handle Roon/Audirvana/HQPlayer tasks better.

 

 

Despite being the most affordable streamer we can offer, we don’t let go of our standards to develop quality products. We still work closely to manufacturers and develop a custom BIOS, designed for audiophiles with intensive listening tests with flagship CD player as reference.

As a result, CoreStream streamer can deliver audio performance that can feel like listening to real music. We don’t build products to be just acceptable in audio system as background music. It must bring out emotion to feel the real sound from your system too.

Before launching CoreStream, we have a few audiophiles visiting our room and demonstrated CoreStream together with CD playback from flagship CD player in our system. Our clients are all satisfied saying it sounds very close to CD.

The reason why CoreStream can sound close to CD was because we implemented foobar2000 setup assistant we launched to help Fidelizer users setting up a streamer and took steps further to optimize for optimal sound quality with CoreStream streamer.

With intensive listening tests and adjustments on custom BIOS and software configuration, CoreStream can become a reference point to demonstrate how audiophiles can feel the real sound with Fidelizer sound experience from CoreStream as a starting point.

CoreStream can stream music with Airplay / uPNP / Roon Core / Roon Ready / HQPlayer NAA / Plays with Audirvana right out of the box and users can request remote support to provide assistance with software configuration and updates.

 

 

With FidelizerOS that shares a lot of similarity with NimitraOS developed in Nimitra streamer, CoreStream can run on lightweight operating system with special version of Fidelizer designed for dedicated streamer product with the following optimizations.

 

CORE #1: HQPlayer NAA daemon / RAATServer
CORE #2: foobar2000
CORE #3: foobar2000
CORE #4: non-audio processes

 

With this configuration, foobar2000 won’t interfere audio thread on Core#1 and won’t share thread with non-audio threads in Core#4. HQPlayer NAA daemon and RAATServer will run as endpoint on Core#1. These audio processes will run at high priority to ensure optimal performance.

As for hardware specifications, CoreStream shares a lot of design from Erawan flagship streamer as below:

CPU: Intel N100 processor (With custom BIOS for optimal audio performance)
Memory: 8GB DDR4 3200MHz dual channel
Storage: Enterprise grade SSD
USB: 2 x USB Audio (blue) / 4 x USB Storage/receiver (black) / 1 x USB Type-C
Ethernet: 2 x 1Gbps
Display: 1 x HDMI / 1 x DisplayPort
Power supply: 100 – 250 VAC
OS: FidelizerOS (Custom Windows 11 Pro 24H2)
Supported streaming platform: Airplay / uPNP / Roon Core / Roon Ready / HQPlayer NAA / Plays with Audirvana
Product features: Remote support / Custom feature request if applicable
Dimension: 140mm x 115mm x 50mm (W x D x H)
Weight: 1.5kg

 

 

CoreStream can deliver streaming audio experience in the way we envision to deliver quality streamer together with Aura medical grade power supply and HyperLink network switch at around $1,000 USD budget which is finally possible now.

The product price will be $699 USD with 30-day money back guaranteed and free shipping until 31st August 2025. You can read more about CoreStream streamer product in details before ordering and happy listening.

 

 

After 8 years of development, Fidelizer’s flagship streamer product called “Erawan” is now ready to be shipped to overseas. It took 8 years because we set the main goal of Erawan to deliver streaming quality that we won’t miss flagship CD transport.

We could have released Erawan sooner and take advantage from Nimitra’s enormous success before COVID-19 but we want to release something that won’t make you miss CD, something that even vinyl lovers will be interested to hear. This is our mission, not business.

 

To make sure Erawan will really deliver quality we strive for, we conducted internal research and development with Esoteric Grandioso K1X which was one of the best CD players in market today. After reaching on-par performance to reference CD in our systems, we brought Erawan to test outside.

We gained a lot of new experience testing products in different systems. Hearing Erawan against Esoteric Grandioso P1X SE + N-01XD SE in bigger room with bigger reference system taught us a lot more about limitations of digital audio. It brought us joy and suffering at the same time to overcome.

 

 

We also tested Erawan with a few $50-100k turntable setup too and our goal expanded to how we can deliver full scale analogue sound experience like that with streaming as medium. We kept researching relentlessly until we success in developing flagship streamer as we envisioned.

With completely new design from ground up for both hardware and software, Erawan can stream old and new music faithfully and bring whole new experience that you can even compare to Nimitra2 and hear the difference in recorded video clip as below.

The biggest challenge in developing flagship streamer is reproducing full scale analogue sound performance in highend audio systems. Many audiophiles often struggle to play old favorite songs in streaming platform because it couldn’t bring the life of that era back.

Erawan will stream your favorite old and new songs faithfully and reproduce every part of music as if you travel back in time and listen to music in that era again. We developed a cutting edge technology to bring the best of old and new technology as below.

 

ErawanOS based on Windows 11 Enterprise LTSC 2024

ErawanOS’ development started since 2019 when we finally found a promising version of Windows 10 that sounds decent after the original NimitraOS version. We have been updating until finalized ErawanOS with official Windows 11 Enterprise LTSC 2024 release.

Since original NimitraOS, we are the first to develop streamer with process core isolation feature into audiophile market since 2016. In ErawanOS, we are the first to develop streamer with core isolation feature at hardware level into market as below.

 

CORE #1: Core Audio / Clock and Timer drivers
CORE #2: Network devices
CORE #3: USB and audio devices
CORE #4: Storage and graphics devices

 

With important hardware devices isolated to different cores at higher priority (except graphics devices), Erawan can finally stream music at higher fidelity with improved performance on both dynamics and transparency.

ErawanOS is also developed from ground up differently from NimitraOS to decrease hardware latency and jitter. There’s a lot of new and unique optimizations, combined with Windows Server 2025 optimizations and internal improvements to deliver full sound similar to real vinyl.

 

 

Flagship quality linear power supply design

Erawan flagship streamer has built-in linear power supply with completely new design for flagship highend audio quality. With completely new circuit design using voltage reference circuit. We can finally reproduce transport quality similar to flagship CD transport level.

Besides new power supply circuit design, we also use highend grade components as below:

-100VA AUDIO GRADE toroidal transformer from Toroidy
-Silicon-carbide diodes from Cree
-Polymer hybrid output capacitor
-Solid core pure copper internal wiring

With new design of flagship linear power supply, Erawan can faithfully reproduce music with fuller dynamics and yet it can reveal more micro detail and decay at the same time. This power supply helps Erawan controlling low frequency to reproduce real analogue performance.

 

 

Next generation of hardware design that can handle high performance applications

In early designs, we used to develop Erawan prototype based on Intel powerful i7 processors to handle high complexity tasks but powerful processor won’t allow us to maintain flagship CD transport level of transparency even with best power supply.

So, we develop a new solution based on more recent technologies and found new sweet spot that can maintain flagship CD transport level of transparency while providing more dynamics with scalable processor design with ultra low latency RAM.

As a result, Erawan can maintain the same principle of being low powered design similar to Nimitra. However, this next generation design is capable of handling powerful tasks like DSD256 upsampling as Roon core and Audirvana for better performance.

We also upgraded clock in motherboard’s chipset and storage to further reduce jitter at more fundamental levels with new technology of components. Now Erawan can have both transparency of low powered and full scale sound of powerful processor, best of both worlds.

 

Separated USB/Ethernet ports for optimal audio performance

Erawan now comes with two separated ethernet ports, 1Gbps and 100Mbps for high bandwidth and low noise applications. Some highend ethernet cables have fast ethernet design for low noise and Erawan is fully compatible with fast ethernet design on 100Mbps port.

USB ports also have high-end grade modification to make onboard USB streaming full and uncompressed dynamics in large room. But if you want to install external USB card, low-profile PCI slot will fit in Erawan based on audiophile cards we tested before.

 

Just like Nimitra, Erawan can work with the following applications from different platforms as below:

 

Windows: Kazoo, Kinsky
Mac: Kazoo, Kinsky
iOS: JPLAY, Kazoo, Kinsky, mconnect Player, Lumin
Android: Kazoo, Kinsky, mconnect Player, Lumin

 

Erawan supports many features such as DLNA/uPNP (Audirvana/JPLAY/mConnect Player), OpenHome (Linn/Lumin), Airplay, Audirvana, HQPlayer, JPLAY, Roon and SqueezeBox ready to be used as plug and play solution.

 

As for hardware specifications, Erawan has gone through a lot of design changes from improved low powered server design to powerful server with flagship processor quality. At the end of the day, Erawan was finalized with these specfications as below:

CPU: Intel Elkhart Lake Pentium N6415 Quad Core processor (Up to 3.0GHz)
Memory: 16GB DDR4 3200MHz dual channel
Storage: Audiophile Grade SSD SLC mode (Optional: 1-4TB SSD with highend grade SATA cable on request)
USB: 2 x USB Audio / 2 x USB Storage / 2 x USB 2.0 side port
Ethernet: 1 x Intel I211-AT 1Gbps / 1 x Intel I211-AT 100Mbps
Display: 1 x HDMI / 1 x DisplayPort
Expansion Slot: 1 x Low-profile PCI Express X1
Power supply: 100 – 250 VAC
Grounding: Chassis ground support with ground conditioning products
OS: ErawanOS (Custom Windows 11 Enterprise LTSC 2024)
Supported streaming platform: Airplay / uPNP / OpenHome / LMS / Roon Ready / HQPlayer NAA (Audirvana, HQPlayer and Roon on request)
Product features: automate library server management / TeamViewer remote support / Web remote
Dimension: 365mm x 307mm x 120mm (W x D x H)
Weight: 7kg

 

This hardware design is finalized and future proof as it can handle Roon and Audirvana with DSD256 upsampling. Even Nimitra that was design 8 years ago which can still keep up with Roon today with firmware updates.

We already sold 5 units of Erawan before global launch so we have a few cases of users with different platforms to make sure Erawan will deliver smooth transition without interruption. As Esoteric Grandioso K1X SE owner, we can proudly say Erawan made these people happy no less than CD/vinyl format.

 

 

The product price will be $8,900 USD with 30-day money back guaranteed and free shipping until 31st May 2025. You can read more about Erawan flagship streamer product in details before ordering and happy listening.
