The Aeon was developed from the 432 EVO High-End model, taking the design further. It shares the dual power supply set-up from Sbooster, but with a high quality SOtM superclock board for optimised USB output. The Aeon also has additional core specific software tuning to minimize jitter and all audio processing now runs on a dedicated core.
The Aeon runs full Roon or Logitech Media Server and our sublime 432 Hz enabled player, which can also play bit perfect to the highest possible quality. It also features a bit perfect Teac CD drive for ripping your CD collection.
432 Hz is one of the ways to tune musical instruments, and is also known as the Tuning Note “A” and A = 432. Music tuned to 432 Hz sounds better than contemporary music which is tuned at A = 440. The famous Stradivarius for example was tuned to 432 Hz according to the Verdi tuning. During 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. 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 432 EVO offer you the possibility to convert your existing music on the fly into the better sounding 432 Hz, without any resolution loss. Several ‘best of show’ awards that 432 Evo have won are the ultimate proof, and recent research by Maria Renold and a group of 2000 people showed that 90% preferred 432 Hz. For purists 432 Evo still offer bit perfect mode on par with the best CD transports or up-sample only mode for those who want to tune the sound. All these modes are live switchable!
The 432 EVO Aeon incorporates a modern power efficient Quad Core CPU with 4 or 8 GB of RAM (8 GB RAM when HWBOOST is selected as option). 432 Evo implement many techniques from the supercomputing world inside the Aeon 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 at 1,000 times per second, greatly improving software jitter, as process switching is minimised.
The Aeon also eliminates typical “chao” found inside the OS of many other servers by using advanced kernel and process tuning configurations not found in any competing product, further lowering software jitter by reducing entropy. This is a remarkable achievement and key to it’s stellar performance.
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. The big advantage of this approach is that the Aeon is future proof. If faster and/or better sounding main boards become available, the customer will be able to upgrade. 432 Evo already offer this to existing customers.
They use a custom realtime Linux OS, refined and tuned by 432 EVO’s owner Frederic Vanden Poel, who is also a senior Linux consultant building with 20+ years of IT experience. The EVO can be on 24/7 and will never run hot, always running cool while sounding analog and very refined.
