In Reply to: RE: Using Rochelle salt to absorb EMI from your homes AC line to supercharge your audio system performance posted by cdc on December 03, 2023 at 12:08:06
Thanks ...US is correct....I'll let you know when do as you suggest
Follow Ups:
do you use paper/masking tape?
Feels like paper. The masking tape is nothing special, just a general purpose 3M brand masking tape.
Thanks for your post.....My system is all Ayre electronics (preamp, amp, silver disc player) with Vandersteen 5A speakers. and turntable with Windfield cart. All components are differentially balanced and am using balanced cables...so that noise doesn't intrude. I treated 4 outlets which power the speakers amp, preamp, and CD. The result was cleaner and clearer picture with more separation of instruments, especially an increase in depth perception . Will continue treating more outlets, but a definite thank you to you.
Yes, keep treating more junctions. The more EMI/EMF that is removed from the AC wiring (across all AC circuits) the better it gets. Eventually ultra fine detail and layering of micro harmonic information becomes available. Noise floor keeps getting lowered as more and more EMI/EMF is absorbed from the AC home wiring.
Eventually from utilizing this process or technique of absorbing EMI/EMF, you will realize that our home's AC wiring is acting like a giant antenna that absorbs high frequency noise. Just be sure to tune each junction before moving on for tonal balance and make sure you do not over damp. You can tell that you over damped if some of the ultra fine detail/resolution is being masked. As you treat more junction points your system will become more resolving.
As the resolution increases it effects different aspects of system performance. From sound stage, to fine then ultra fine micro detail, to micro and macro dynamics, to separation of all sounds, to space of venue, reverb, attack and decay trailing detail and so forth. You will understand as you treat more and more junctions. Will likely improve any video devices in your home like TV monitor or computer monitors.
Look forward to reading or knowing how it works for you. If you have questions, just ask here or in that thread where the DIY post is. Have fun, it is a very simple but interesting project.
Do you have a suggestion as to where I get the scale....thanks
Fastest is from Amazon. You want a .01 precision digital scale. I got mine from Aliexpress (pic is of my scale), lower price but have to wait 2 weeks vs a few days from Amazon. Mine is a 500g max weight, .01 accuracy. Below is a link to a Amazon option, which I do not own so look at the reviews. I will also provide a link to the small zip lock bags I use and purchased from Amazon and Rochelle salt I use but available from Amazon.
Amazon .01 precision scale option:

Amazon bags I use (NOTE: this project only needs the 2 smaller sizes):

Rochelle salt I use but sold on Amazon (I buy 1-2 lb at a time from eBay):
* 4oz ($10.99 includes shipping):

* 8oz ($14.29 includes shipping):

Couldn't agree more. I had to redo all the plates I had previously treated because I "thought" the scale I use for coffee roasting would be good enough. Well, it wasn't even close and that's on me. The first key step for a successful Rochelle salt tweak is to get a scale accurate to .1 gram. They're not that expensive as already noted.
Glad you figured a way to implement the tweak. I have a few questions for you that may also help others contemplating the tweak or is utilizing the tweak:
* how much Rochelle salt are you using at the Hot and Ground sides of the junctions?
* have you treated all junctions in your home or just some?
* what are you hearing from your system after implementing the tweak? Basically what has the tweak done for you?
Thanks for the feedback! I shared this tweak hoping as many people as possible got to experience it.
1.Used the 1 gram(hot) .5 gram (neutral) formula.
2.33 duplex and single switch plates treated.(probably 80%-90% of what's possible in a 1360 sq. ft. house)
3. Listening sessions have been limited and I haven't even listened in my smaller room set up yet. So briefly after listening to 3 or 4 CD's in my larger set up... lower noise floor, increased clarity, better separation of instruments and vocals in the soundstage...IOW, a little less confusion when things get complex. Individual vocals and instruments that are highlighted in a recording seem to "pop" and be more vivid.
This all said, much more listening is in order in both systems to possibly come up with a more accurate assessment, but I certainly hear no downside at this point.
Meaning is your system more resolving now? And what does "IOW" mean?
IOW = "in other words"
Yes, initially more resolving as I've hinted already. That said, I just went thru a major flooring project and with the rooms empty, it made access to duplex and switch plates a lot easier. Now with everything put back together,(finally) I'll have more time to further evaluate the effects of this tweak in both systems. Thx for your discovery and input in regard to this project.
