Using custom BIOS and kernel tuning, the EVO actually shuts down chip functionality on the motherboard, so it acts like a software defined custom motherboard. This is a remarkable achievement and key to it’s stellar performance. The Master also eliminates typical “chaos” found inside the OS of other servers by using advanced kernel & process tuning configurations not found in any competing product, further lowering software jitter by reducing entropy. We implement techniques from the supercomputing world inside the Master to guarantee a stellar audio performance: the audio decoders and 432 Hz processing run on a dedicated core, and will never run out of CPU cycles or have to fight with other processes.The dedicated audio core runs a custom clock scheduler which doesn’t interrupt the critical audio processes 1000 times per second, greatly improving software jitter, as process switching is minimized. The 432 EVO Master incorporates a modern power efficient quad core CPU updated in Q4 2020 with 8 GB of RAM, and now twice as fast as N4200 based competitors. Several best of show awards we have won are the ultimate proof, and recent research by Maria Renold and a group of 2000 people showed that 90% preferred 432 Hz.įor purists we still offer bit perfect mode on par with the best CD transports, or upsample only mode for those who want to tune the sound. The 432 EVO offer you the possibility to convert your existing music on the fly into the better sounding 432 Hz, without any resolution loss. A higher pitch such as our current A = 440 standard sounds sharper, louder and more “fresh”, but also more aggressive, which is not a quality audiophiles are looking for. The famous Stradivarius for example was tuned to 432 Hz according to the Verdi tuningĭuring historical periods when instrumental music rose in prominence (relative to the voice), there was a continuous tendency for pitch levels to rise, also known as the pitch inflation. Music tuned to 432 Hz sounds better than contemporary music which is tuned at A = 440. No reclocking: our high-end USB board is directly clocked (not reclocked) from a dedicated ultra low jitter clock board, and both are powered independently.Ĥ32 Hz is one of the ways to tune musical instruments, and is also known as the Tuning Note “A” and A = 432.All critical area’s of the server have their own power supply.Custom remote supported Linux with realtime kernel, and dedicated cpu core for audio, and separated cores for the library management (Roon or LMS).Bit perfect mode, upsample only mode or upsample with 432 Hz post-processing.Ultra high-end upsampling with 10 selectable and tweakable upsample filters.Three high-end silver color coded DC cables are included. True triple linear power supply with triple AC filtering, triple shielded transformers for faster transient performance compared to designs with a shared transformer, triple dual stage DC regulation, with buffering inside the triple DC cables.

Our dual enclosure chassis has a true triple linear power supply with no shared transformer and utilises the very best components such as gold plated PCB’s, and is a major upgrade over our AEON model (from which existing customers can upgrade). It immediately won best of show from both AV Showrooms and Hifi Pig. Tried and tested in world class systems and designed according to the most extreme audiophile standards for ultra low jitter and low noise, the Master was introduced at Munich High End 2017. It can easily surpass any other digital source, including the most exclusive digital CD transports, sounding more like analoge sources with no hint of digital harshness.
The 432 EVO Master is our flagship and a best in class music server with a cost no object performance.
