Well, I must first credit Steve Deckert of Decware for turning me on to the idea of 432Hz and providing the background information to support why this frequency deserves recognition.
I’ve read Steve’s white paper on the subject (http://www.decware.com/newsite/DECWARESOUND.pdf). I also did independent research and perused the many sources of information that contribute to this subject matter.
As a result, I purchased a 432 EVO AEON music server. Why did I purchase this server? Well, the name kind of shows its hand. It is a music server that uses a special technique to retune 440Hz music (99.999%+ of all we listen to) to 432Hz. They use a proprietary technique to achieve the retune, so it is not simply done by changing the playback speed or pitch which has shown to produce undesirable artifacts. Pitching is not enougth! Doing so just shifts everything 8Hz lower. But the tempered scale is still 440Hz based! (e.g. A4 is now 432Hz, but A5 is not 864Hz, it’s 432Hz + 440Hz). If interested you can read up at www.432evo.be. It is a Belgium company.
Anyway, I have had this server in my system for four months. I am able to turn the 432Hz retuning process Off and On at will. The beauty of this feature is in it’s ability to convert all digital music sources to 432Hz in real-time, including streamed music from Spotify, Tidal, Qobuz, etc.
I have done the A/B/A testing and there is something to this. The 432 EVO server is a high-end music server with top-notch engineering, parts, and custom software so even if I did not invoke the 432Hz processing, it is a KILLER server with just gorgeous sound. With the 432Hz retune feature disabled, it is bit perfect. Just to put it in perspective, I use (3) discrete linear power supplies to power this server. Each LPS is assigned a very specific duty: (1) to power the server main board; (1) to power the SoTM USB output audio card; (1) to power the SoTM Superclock board that drives the USB card timing.
Anyway, there have been some scientific studies done on the effects of 432Hz vs 440Hz audio. Maria Reynold did extensive research on the topic and eventually published a book. Her findings concluded 90% of test participants blindly preferred 432Hz over 440Hz.
For the last 4 months, 100% of my digital streaming has been processed to output audiophile worthy 432Hz music and I can unequivocally state that I prefer the processing function enabled as opposed to disabled. If I was to sum up my observations by comprising a single statement, I would say that the 432Hz music drastically reduced my need to skip tracks, turn down the volume, look for a higher-res variant, or accuse my system of aurally violating me.
Here is an interesting video on 432Hz that was just brought to my attention:
In 100% honest disclosure, I did pick the 432Hz version of the acoustic guitar solo as my preference. (Please ignore/discard any of the non-music related content contained within this video). And most importantly, take it for what it is.
I intentionally refrained from making any “knee jerk” statements or proclamations based on the fact that I was genuinely unsure whether or not it had merit. That skepticism has officially been put to reset. There is something to this 432Hz stuff and my experience over the last several months substantiates (for me) what is being claimed by the legitimate players in this arena.
Subjective? Certainly. But, unless you’ve been subjected to the A and the B, you can only speculate. That said, it’s still worthy of sharing.
