The 432 EVO Essence is the all-in-one server with integrated high-end 24/192 DAC using an oven controlled clock for low jitter, and also has a high-end SP/DIF coaxial and optical output. Furthermore it’s upgradeable as you can use most external DAC’s, as it also supports SP/DIF, USB and HDMI DAC’s out of the box.
The 432 ESSENCE features a high-end soundcard from Asus, which also exists in a DAC version. The DAC version of this soundcard won EISA awards, and after reading their review “an honest and compelling sound that puts many traditional hi-fi marques to shame!”, we wanted this technology in the integrated model.
The DAC inside the Essence easily surpasses many other similarly priced standalone DAC’s, sounding closer to high end analogue with no hint of digital harshness thanks to the 432 Hz plugin.
The Essence runs 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.
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 the 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 we 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 we still offer bit perfect mode on par with the best CD transports, or upsample only mode for those who want to tune the sound. All these modes are live switchable.
The 432 EVO Essence features a high-end 24/192 DAC card from Asus. The DAC chips used are the Texas Instruments PCM1792A which deliver an industry leading signal to noise ratio of 124dB.
Texas Instruments uses it’s own DAC architecture which has a built-in digital clock, and in the Essence is combined with a TCXO (temperature compensated crystal oscillator) for the lowest jitter, a feature usually found in much more expensive DAC’s.
The DAC board also uses high fidelity low dropout (LDO) regulators, and several capacitors are from WIMA. The output section uses MUSES 8920 and 8820 opamps, which are J-FET amplifiers from New Japan Radio Co.
The Essence has high-quality RCA analog outputs, a combined optical & high-end coaxial S/PDIF output port, and also supports external DACs with USB or HDMI inputs.
The USB ports when hooked up to one or more USB DAC’s can be combined with the internal DAC, to create more than one output zones. The analog output RCA and S/PDIF (coaxial and optical via an adapter) can work simultaneously on the 432 EVO ESSENCE as one output zone!
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 power supply is silent and free from any transformer noise.
