The 432 evo has been taking over the server market in europe and the servers employ a tremendos amount of novel technology
They have 4 different models with ever improving sound quality
Starting at the 3k 432 evo standard
All model Designed from the ground up as a state of the art roon core and player
Un like any other server they are upgradeable from one model to the next
The aeon model 6k compares with an innous statement yet costs half as mutch
We offer 2tb ssd for the price of others 1tb
All service is performed in the usa

432
The 432 in 432 EVO refers to 432 Hz, and is one of the possible frequencies used for tuning acoustical instruments in the keynote A. Over the coarse of the last centuries, the tuning for keynote A has changed, from 415Hz via 432Hz to the current 440Hz, ever since WW2. More specific to this review, it is processing software developed by Klinkt Beter, based on research done by Maria Renold on the perceived differences between 440Hz and 432Hz. Maria’s research was carried out with a group of more than 2000 people, which were presented pairs of tones along with their octaves, at 440Hz and 432Hz, and over 90% of the people chose 432 as sounding, amongst others, more “peaceful” and “pleasing”.
Converting to 432 Hz can be done in a number of ways, and although I have not tested any of the alternate methods myself, most of them are said to result in music that sounds more relaxed, but also off-tune, destroying micro detail and spectral imaging in the process. For example the method using normal pitch shift which lowers the pitch but retains tempo, will apparently cause resolution loss and kill the upper harmonics. Another method to convert to 432 Hz is by using speed shift, which is best demonstrated by playing a record on a turntable at a slightly lower speed. The 432 Hz method does exactly the same and lowers the speed on the fly in the digital domain, to map A=440 back to A=432.
Although this may sound simple, according to Klinkt Beter, it took them considerable time to implement an algorithm that was both very efficient and free or artefacts. As a side note, remapping to A=432 with the default setting for the plugin only works well if the source of the music is indeed A=440. Most modern pop/rock/electonic/dance/jazz is produced at A=440 Hz, but classical orchestras tend to tune even higher than A=440 and for those instances, there is a setting that can be made to choose the base frequency for the 432 plugin. For my purposes (I don’t listen to classical much), I left it at its default setting which is 440 to 432 conversion and assumes the original music is produced in A=440
One could argue that the EVO is changing the music from how it was intended, and this is something that I cannot deny. But this is very much a theoretical matter. I always feel that if it sounds right, it is right. Whether or not it sounds right to you, is something that needs to be experienced. In any event, this method absolutely has some very obvious benefits, about which I will report further below.
The 432 EVO utilitizes the 432 software in the shape of a plugin that processes the music from 440 Hz to 432 Hz in real time. This means that the unit still plays all formats, up to DSD256. Incidentally, while most USB chipsets are limited to 24/192, the EVO will play any file in PCM up to 24/768 and up to DSD256 via DoP when playing 1:1, and PCM up to 24/768 and DSD up to DSD256 output as PCM when using 432 processing.
