It sounds very close to flagship CD player
When Fidelizer Nimitra Classic was launched, it was for the purpose to make highend streaming solutions more affordable as customers can buy Nimitra Classic + Nikola Classic + EtherStream instead of only Nimitra Signature only.
With successful launch of Fidelizer Aura medical grade power supply and HyperLink network switch, Fidelizer CoreStream streamer can make highend audio streaming even more affordable with CoreStream + HyperLink + Aura instead of Nimitra Classic only.
Streaming music with Fidelizer’s sound experience
To develop the most affordable streamer, the biggest obstable is software cost. For Roon and Audirvana, we can provide support with user’s license to get the most of CoreStream. As for DLNA/uPNP streaming, we designed new Fidelizer sound experience as below.
foobar2000 with CoreStream optimizations
Fidelizer released foobar2000 setup assistant for a while and it’s been working well to help people setting up PC as dedicated streamer in one click. With CoreStream, we took steps further to bring sound experience closer to feel the real sound.
foobar2000 with built-in output will sound a bit harsh with some glare for audiophiles who listen to vinyl mostly. To resolve digital harshness, we fine-tuned CoreStream with our custom configuration on foobar2000 to get rid of digital glare.

You can use DLNA/uPNP streaming with Audirvana/JPLAY/mConnect to enjoy Fidelizer sound experience with richful sound, dynamics, and scale. We also compared playback against flagship CD player with our clients to make sure they will have satisfying streaming experience.
FidelizerOS based on Windows 11 Pro 24H2
FidelizerOS shares a lot of similarity with NimitraOS developed in Nimitra streamer. They both have ultra lightweight operating system and special version of Fidelizer designed for dedicated streamer product but FidelizerOS won’t have specific optimizations for Nimitra.
NimitraOS has its own real-time optimization software with special fine-tuning and optimizations. FidelizerOS will utilize on special version of Fidelizer to handle optimizations differently. CoreStream will have core assignment for the following processes as below.
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.
Custom hardware and BIOS for audiophiles
The reason why Fidelizer Nimitra streamer products can deliver highend audio performance like no others is because we develop closely with a manufacturer to get enterprise grade of components and develop a custom BIOS for audiophiles with intensive listening tests.
We also did the same with CoreStream despite being the most affordable streamer because this is our standards and our DNA to make sure Fidelizer products will deliver with real sound performance starting from the very root of streamer.

We optimized deeper level of BIOS file to adjust specific configuration options that aren’t shown in BIOS settings for optimal sound quality with great reliability. We value both quality and safety for good sound to last for years to come.
This is the reason why CoreStream can make audiophiles satisfied even after listening to CD from highend CD player. It’s because we take streaming seriously and won’t settle for just being acceptable as background music.
Roon Core / Roon Ready support
CoreStream will come with Roon core and Roon Ready feature preinstalled. You can migrate Roon from backup to CoreStream right away or use CoreStream as endpoint with Roon Ready feature. We can also provide remote support with setup and configuration too.

HQPlayer NAA Daemon and Airplay support
CoreStream also come with HQPlayer NAA and Airplay support. If you have powerful PC running HQPlayer, you can stream to CoreStream as endpoint right away. Airplay in CoreStream is also optimized for optimal sound quality too.
Since CoreStream runs on Intel N100 processor with AVX2 instructions in turbo mode, you may consider moving HQPlayer to CoreStream and see if your configuration can work with CoreStream for more satisfying results.
Partnered with trusted audiophile software products
Fidelizer promises to deliver highend audio sound quality standards to audiophiles who trust since 2016. We are the first company who introduced highend streaming software solution JPLAY to audiophile worldwide as hardware product and we continue to do so.
We never stop pursuing for best possible sound quality and won’t compromise sound quality for business interests. If Fidelizer is partnered with any company, it will always be about audiophile’s best interests and partnership will end when they can no longer maintain their standards.
Online remote support to tailor custom needs

After product delivery, there might be cases like installing drivers for new devices after purchasing CoreStream. With remote support built-in, CoreStream users can receive remote assistance immediately and implement more possible solutions to enjoy the music better.
