SKU: N/A Category: Brand:

The 432 EVO AEON is the server directly below the top of line Master model. The Aeon shares several features with the flagship model and is offered at a lower price point. Even so, it easily surpasses many other similarly priced digital sources, sounding closer to high-end analogue with no hint of digital harshness.

 The Aeon was developed from 432’s EVO High-End model, taking the design further. It shares the dual power supply setup from Sbooster, but with a high-quality SOtM super clock board for optimised USB output. The Aeon also has additional core-specific software tuning to minimize jitter, and all audio processing now runs on a dedicated core.

The 432 EVO Aeon runs full Roon or Logitech Media Server 432’s 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. Aeon can be upgraded later to the Master at a later stage if required.

432 EVO AEON Information:

• Uncompromised CD ripping using a bit-perfect Teac rip facility.
• 2 TB full SSD storage on a spring suspension system, with SATA noise filtering and SATA protocol tweaking for lower EMI.
• Dual linear power supplies, one 12V and one 9V, each with AC filtering, toroidal 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.
• 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 a real-time kernel, and dedicated CPU core for audio, and separated cores for the library management (Roon or LMS).
• Critical area’s of the server have their own power supply.
• No reclocking: the high specification USB board is directly clocked (not reclocked) from a dedicated ultra-low jitter clock board, and both are powered independently.



432 EVO Aeon Specification:

Digital output
Super clock based dedicated USB 3.0 output supporting USB Audio Class 2.0 to connect to your USB DAC
Network streaming with real-time scheduling to any Roon endpoint and Logitech / Squeezebox based players
1x RJ45 for real-time clocked gigabit supporting true gigabit ethernet ISP’s
1x ultra-high-end low jitter super clock based USB DAC output
2x USB 3.0 ports for backup or connecting additional USB DACs
2x USB 2.0 ports for connecting additional USB DACs
VGA, DVI, HDMI and keyboard/mouse service ports – normally never needed as the EVO is VPN supported
Logitech Media Server
All common formats including DSD, WAV, FLAC, MP3, Ogg Vorbis, aac, … Passthrough of MQA
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.
Logitech Media Server
Ogg Vorbis is supported by Spotify Passthrough of MQA towards MQA DAC when using bit-perfect mode
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.
Bitperfect 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 rates:
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
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
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
