The 432 EVO STANDARD model is our entry level model, for those who want the full 432 Hz plugin functionality at an affordable price point, or those who want to ultimately own the HIGH-END or AEON model, and start with the STANDARD to upgrade later.

 It has the same software as our other models including the same Linux OS with real time kernel, but in this case the software has basic tuning. 

On the standard, we use the motherboards USB output to connect to your USB DAC. 

In the High-End & Aeon models we go further by having a dedicated USB output card, and on the Aeon & Master models this USB output is  superclock driven. In those models, the OS & under the hood software tuning, invisible to the end-user but clearly audible, is also much more refined.

 However the USB output of the STANDARD combined with the realtime kernel and it's single Sbooster BOtW MK II true linear power supply is already a big step up compared to those who use a PC, MAC (inc Mac Mini) or laptop as their source feeding a USB DAC. 

The STANDARD can run 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.

 Uncompromised CD ripping using a bitperfect Teac rip facility.
• 2 TB SSHD storage on spring suspension system: ultra low noise laptop HDD with SSD caching.
• Single 12V linear power supply from Sbooster, the Sbooster BOtW MK2. One of the best power supplies on the market, with low voltage drop, high-quality transformer and high-quality DC cable.
• 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 realtime kernel.
• Spring suspension system: the 2.5″ low-noise 2 TB SSHD is mechanically decoupled using springs to drastically reduce vibrations inside the chassis.
AUDIO OUTPUTS
Digital output Several motherboard USB outputs supporting one or more USB Audio Class 2.0 DAC’s
Network streaming with realtime scheduling to any Roon endpoint and Logitech / Squeezebox based players
CONNECTIVITY
Ethernet 1x RJ45 for realtime clocked gigabit supporting true gigabit ethernet ISP’s
USB 4 ports available for USB audio & backup
2x USB 3.0 ports for backup or connecting additional USB dac’s
2x USB 2.0 ports for connecting USB dac’s
HDMI HDMI port supporting HDMI dac’s and surround processors / receivers
KVM VGA, DVI, HDMI and keyboard/mouse service ports – normally never needed as the EVO is VPN supported
OPEN FILE FORMATS
Logitech Media Server All common formats including DSD, WAV, flac, MP3, ogg vorbis, aac, … Passthrough of MQA
Roon MP3, WAV, WAV64, AIFF, FLAC, Apple Lossless, OGG, and AAC at resolutions up to 32 bit 768kHz. Roon also supports DSD64, DSD128, DSD256, and DSD512 in the DSF and DFF formats.
DRM FILE FORMAT
Logitech Media Server Ogg Vorbis as supported by Spotify Passthrough of MQA towards MQA DAC when using bitperfect mode
Roon MQA first unfold supported & 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 EVO’s 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
Bitperfect mode No audio transformations occur, unless DAC does not support sample rate or bit depth of format, otherwise true bitperfect matching or even beating the most exclusive CD transports
Upsampling-only Output most DSD & PCM formats in any input samplerate as 24 bit or 32 bit output in one of the following output samplerate:
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 up to 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 his 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

HARDWARE
Ripdrive Hand tested Teac slot-loading, tested with at least 5 retail CD’s which are known to cause rip issues on some drives. All CD’s must past our extreme test.
Default storage Ultra low noise laptop 2 TB SSHD (hybrid HDD+SSD) on spring suspension system, with SATA noise filtering and SATA protocol tuning for lower EMI
Storage upgrades Optional 2 TB SSD or 4 TB SSD or 2x 4 TB SSD merged as a virtual 8 TB instead of 2 TB SSHD is possible. Please ask your reseller 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 4 GB, large enough for music collections up to 2 TB
