Your music.
At the highest quality.
Always.
gtCore turns a Raspberry Pi into the heart of your Hi-Fi system. Pay once, listen forever — bit-perfect, all sources in one place. Or choose gtLine light: ready-to-use hardware, immediate plug & play.
Plug & Play
Connect it, switch it on, use it. No command line, no complex configuration. Your HI-FI system is connected and ready in minutes.
Uncompromising quality
Listen to your files in their original high-resolution formats. No conversion, no loss. The signal reaches your headphones exactly as it was recorded.
Your library, your rules
Connect your drives and build a massive personal archive. Works without internet, without subscriptions, forever. Your files, under your control.
Everything in one interface
Radio, local files, streaming: all accessible from the same screen, from your tablet or home smartphone. A refined experience, without aesthetic compromise.
Everything you need to listen well
gtCore is not just a player. It's a complete audio infrastructure, built for those who refuse to compromise on quality.
Multiple sources, one access point
gtCore is the audio hub of your home: music streams from the device itself — no third-party apps, no external connections needed. Your personal library is managed directly by the software, which acts as a built-in NAS. Dozens of sources supported and constantly growing.
High-resolution formats, bit-perfect playback
The audio signal reaches your DAC exactly as it was mastered — no conversion, no unwanted resampling. gtCore handles native PCM, DoP (DSD over PCM) and native DSD playback: the optimal mode is selected automatically based on the connected DAC.
Local music library
Connect external drives to the device: gtCore automatically indexes your library, manages metadata, and displays artwork. Works offline, no cloud, no subscriptions. Forever.
Control from smartphone or tablet
No app to install. Controlled from any browser on your home network — smartphone, tablet, PC. The interface is optimised for touch and designed for the sofa.
Search and playlists
Search across artists, albums and tracks on all sources simultaneously. Create playlists, manage the queue, organise your music the way you like.
Updates included
The system updates automatically. New sources, interface improvements, support for new formats: everything arrives without manual intervention.
Ready in three steps
From the box to listening in less than half an hour. No technical support needed, no documentation to read.
Get the hardware
A Raspberry Pi (Pi 4 or newer recommended) and an SD card — that's all you need to get started.
Connect and listen
Connect the Raspberry to your network and open http://gtcore.local in your browser: register and you're in. Choose your sources, organise your library, build playlists — music, finally, the way you want it.
One fixed price. No subscription.
Try it before you decide: 30 days free, no credit card, no commitment. All it takes is a Raspberry and an SD card — download gtCore Burner and you're already listening.
Then choose how to continue: just the gtCore license for your own Raspberry, or gtLine hardware with gtCore already installed. Either way, a single one-time payment — never a subscription.
