The 432 EVO Master is the flagship model 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 analogue 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 432 EVO Master was introduced at Munich High End 2017. It immediately won best of show from both AV Showrooms and Hifi Pig.
The 432 EVO Master 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 the AEON model. The MASTER runs a full Roon Media Server and can be designates as a CORE. 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.
432 EVO Master Information:
| • Uncompromised CD ripping using a bit perfect Teac rip facility. |
| • 2 TB full SDD on spring suspension system, with SATA noise filtering and SATA protocol tuning for lower EMI. |
| • True triple linear power supply with triple AC filtering, triple shielded transformers for faster transient performance compared to designs with a shared transformer, triple dual stage DC regulation, with buffering inside the triple DC cables. Three high-end silver colour coded DC cables are included. Zero hum. |
| • Ultra high-end up sampling with 10 selectable and tweakable up sample filters. |
| • Bit perfect mode, up sample only mode or up sample with 432 Hz post-processing. |
| • Custom remote supported Linux with Realtime kernel, and dedicated CPU core for audio, and separated cores for the library management (Roon or LMS). |
| • All critical area’s of the server have their own power supply. |
| • No re clocking: our high-end USB board is directly clocked (not re clocked) from a dedicated ultra low jitter clock board, and both are powered independently. |

| 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 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 | ||
| 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 |
