432 EVO High-End Music Server
Range £4,250
Description
The 432 EVO High-End model has similarities to the Aeon model, but has an integrated clock on the high-end USB output board instead of a dedicated superclock board.
The High-End has a dual power supply like the Aeon, but with the Aeon it’s dedicated audio grade USB output is powered independently of the server’s IT parts. Even so, the High-End easily surpasses many other similarly priced digital sources, sounding closer to high-end analogue with no hint of digital harshness. The High-End model can be upgraded later to the Aeon or Master.
Standard Free UK Delivery Over £75 (3-5 working days)
The 432 EVO High-End model was developed from the 432 EVO Standard model taking the design further by implementing a dual Power Supply set-up from Sbooster. The High-End was also the first model, which used the spring suspension system.
The High-End can run full Roon or Logitech Media Server and the 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.
Key Features
- Uncompromised CD ripping using a bitperfect Teac rip facility.
- 2TB SSHD storage on spring suspension system: ultra low noise laptop HDD with SSD caching, with SATA noise filtering and SATA protocol tweaking for lower EMI.
- Dual linear Power Supplies, one 12V and one 9V, each with AC filtering, torodial transformer for faster transient performance compared to designs with a shared transformer, dual stage DC regulation and with buffering inside the DC cable attached to each Power Supply.
- Low noise audio grade dedicated USB 3.0 output supporting USB Audio Class 2.0 to connect to your USB DAC.
- Ultra high-end upsampling with 10 selectable and tweakable upsample filters.
- Bit perfect mode, upsample only mode or upsample with 432 Hz post-processing.
- Custom remote supported Linux with real-time kernel.
- Critical area’s of the server have their own Power Supply.
- Spring suspension system: the 2.5″ low-noise 2TB SSHD is mechanically decoupled using springs to drastically reduce vibrations inside the chassis.
432 Hz Tuning
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!
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, 4TB or 8 TB of total SSD storage.
HD Storage
The 432 EVO Aeon 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 Aeon.
USB DAC Output
Connects to your USB DAC.
Single SBooster External 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!
The Sbooster power supplies are perfect for this purpose and offer a very stable 12 Volt supply, from which the 432 EVO Standard draws less than a third of what the supply can provide.
When upgrading to Aeon or High-End, a second Sbooster BOtW will be added, as well as additional internal parts and the software tuning of those models will also be activated when upgrading. With the 432 EVO server line-up, you can start at your own budget and upgrade later
Roon

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

iPeng Controller
LMS users can use several control apps, including iPeng or the LMS web interface.
SqueezePad Controller
Squeezepad is another controlle and like iPeng can control the LMS library manager.

|
MQA first unfold supported and any MQA feature in Roon As MQA does not recover any new audio data in the second unfold, second unfold can be replaced by 432 EVOs own upsample which also can support minimum phase rendering with one cycle of post-ringing, or the superior sounding Archimago minimum phase filter. |
| AUDIO TRANSFORMATIONS | ||
| Bit-Perfect Mode: | No audio transformations occur, unless DAC does not support sample rate or bit depth of format, otherwise true bit-perfect matching or even beating the most exclusive CD Transports | |
| Upsampling-Only: | Output most DSD & PCM formats in any input sample-rate as 24 bit or 32 bit output in one of the following output sample-rate: 44.1K, 88.2K, 176.4K, 352.8K and DXD, 706.6K 48K, 96K, 192K, 384K, 768K |
|
| 432 Hz Mode: | Same as upsampling mode, but with 432 Hz processing without resolution loss. 432 Hz and upsampling are a combined one step algorithm, therefore no additional load is caused on the CPU when using 432 Hz mode compared to upsampling | |
| SUPPORTED TUNING TRANSFORMATIONS USING 432 Hz MODE | ||
| Input Pitch: | 440 Hz upto 445 Hz in one step increments Other pitches can be added by special request |
|
| Output Pitch: | 415 Hz 426 Hz 430.5 Hz (Equal Tone Temperament) 432 Hz (Verdi’s A, Pythagorean Temperament) 440 Hz (today’s Concert Pitch) → used for upsample-only mode 444 Hz |
|
| Supported Input Formats: | Any audio and file format from local files on the internal storage on the EVO or a NAS, internet radio, on demand streaming services such. 444 Hz mode not compatible with live internet radio |
|
| UPSAMPLING RECIPES For Upsampling-only and 432 Hz modes |
||
| Linear Phase: | User tunable linear phase filter, including tuning of processing buffer size and several precision options. All frequencies have the same delay through the filter. | |
| Minimum Phase: | User tunable minimum phase filter, including tuning of processing buffer size and several precision options. No pre-ringing. Post-ringing can be regular long tail “minimum-phase” without aliasing or reduced MQA / Ayre inspired one cycle of post-ringing with free bonus aliasing, create pseudo ultrasonics. |
|
| Intermediate Phase: | The only server on the market supporting Archimago’s Intermedia Phase upsampling, the most ideal filter with mainly post-ringing and no phase issues within the audible range. 432 EVO implements the original recipe and two improved variants of this filter |
|
| AUDIO SAMPLE RATES | ||
| Sample Rates: | All common multiples of 44.1 and 48K All common DSD formats |
|
| Bit Depths: | 16, 24 and 32 bit |

| Storage Upgrades: | Optional 2TB SSD or 4TB SSD or 2 x 4TB SSD merged as a virtual 8TB instead of 2TB SSHD is possible. Please ask us for pricing. | |
| CPU: | Model with HWBOOST: J4205 tuned to a more constant power draw for lower software jitter. More modern and faster than many competitors who use the old N4200 Model. Without HWBOOST: non-disclosed quad core CPU slightly slower than the J4205, but still fast enough for Roon | |
| Memory: | Model with HWBOOST: 8 GB, plenty for Roon even when importing larger collections. Otherwise 4GB, large enough for music collections upto 2TB | |
