Om 432 EVO Master

The 432 EVO Master is our flagship and a best in class music server with a cost no object performance. 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.

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 immediately won best of show from both AV Showrooms and Hifi Pig.

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). The MASTER 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.

Dedicated Core

The 432 EVO Master incorporates a modern power efficient quad core CPU with 8 GB of RAM.
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 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. 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 Master is future proof. If faster and/or better sounding main boards become available, the customer will be able to upgrade unlike may of our competitors. We already offer this to existing customers.

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 on 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.

Linear Power Supply
The importance of a pure and clean power supply for digital audio cannot be stressed enough. Digital audio’s enemy is noise, and much of that comes from poorly designed power supplies or cheap SMPS (switched mode power supplies). In fact a dirty power supply can not only ruin the sonic performance of a server, it can also inject noise down the mains to infect the rest of your system!

We thus take the design of our power supplies extremely seriously. The Master has a true triple independent power supply. Instead of offering masses of dependent DC rails from one transformer, every output rail in the Master has a separate AC filter, medical grade shielded custom transformer and dual stage DC buffering.

The second part of the DC buffer is inside each of the three bundled color coded silver DC cables, leading to a very short current paths towards the dedicated USB output board and superclock board, which is just a few centimeters. The “IT” parts inside the server also have their own dedicated power supply, with DC filtering between storage and main board, acting as a noise firewall for the moving parts inside HDD’s, or the PWM converters in SSD’s. As we use 2.5 inch models, the electrical & mechanical noise is already drastically lower compared to normal consumer drives.

Using a triple design with 3 transformers leads to much faster transients compared to a shared transformer. The power supply is also free of any transformer noise.

Linux
432 EVO uses a custom realtime Linux OS tuned for ultra low software jitter and reduced entropy.

Solidstate Drive
The 432 EVO can be optionally be ordered with single or dual noise filtered audio grade SSD’s, leading to a 100% silent solution. Can be ordered with 2 TB, 4 TB or 8 TB of total SSD storage.

HD Storage
The 432 EVO Standard comes has a 2TB low noise hybrid storage on a custom spring suspension system combining the best aspects of HDD’s and SSD’s in a single drive. Full SSD’s are also possible.

Bit Perfect Ripper
The bit perfect Teac rip drive is hand tested and compared against test CD’s for perfect operation.

Hardware Boost
The HWBOOST option doubles the RAM, and has a faster CPU and better clock. It must be ordered as an option with the High-End.

Super Clock
Our MASTER does not reclock the ultra low noise USB output, but clocks it directly with a dedicated super clock board.

USB Tuning
As no hubs are used, the audiophile USB output is controlled in Linux and custom tuned to get the highest realtime priority.

Roon
Comes pre-installed with a recent full Roon Core (not just endpoint). A separate Roon license is required.

Tidal streaming
Compatible with Tidal subscription-based music streaming service that combines lossless audio and high-definition music.

Qobuz streaming
Compatible with Qobuz streaming service with more than 40 million tracks available, and also offers true 24 bit streaming.

Internet Radio
Supports thousands of internet radio stations, and common formats including AAC, AACv2, MP3 and lossless FLAC stations.

Logitech Media Server
LMS is a very stable music server with two decades of software improvements, and is still supported.

Spotify
Compatible with Spotify, currently the biggest digital music service that gives you access to millions of songs.

iPeng controller
LMS users can use several control apps, including iPeng or the LMS web interface.

SqueezePad controller
Squeezepad is another controller, and like iPeng can control the LMS library manager.
