![]() ![]() Digital audio’s enemy is noise, and much of that comes from poorly designed power supplies or cheap SMPS (switched mode power supplies). The importance of a pure and clean power supply for digital audio cannot be stressed enough. The EVO can be on 24/7 and will never run hot, always running cool while sounding analog and very refined. ![]() We 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. We already offer this to existing customers. If faster and/or better sounding main boards become available, the customer will be able to upgrade. The big advantage of this approach is that the Aeon is future proof. 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 Aeon also eliminates typical “chaos” found inside the OS of many 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 Aeon to gaurantee 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 Aeon incorporates a modern power efficient quad core CPU updated in Q4 2020 with 8 GB of RAM, and 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. 432 Hz is one of the ways to tune musical instruments, and is also known as the Tuning Note “A” and A = 432. ![]()
