As for quieting other appliances ...

Audio Prism used to make a product called Quiet Line Filters. These are basically a series of X-rated caps inside a small plastic box that you plug into an outlet. I think they may have also had a varistor inside for surge suppression, but I'm not sure. In any case, you can make one yourself for next to no money. You just need to buy some x-rated caps and varistors then solder them together and plug them into the remaining electrical outlet by your fridge, washing machine, humidifier, etc. Basically any appliance that might cause a surge when it turns on. I found that using those small plastic outlet safety plugs that you get to protect little kids form sticking a knife into them works really well to hold the long legs of the caps in the outlet.

OF course you can source some quiet line filters and use them if you don't know how to solder or don't want a DIY solution.

I suggest the following x-cap values => 1.0uF, .1uF, .01uF all together in parallel.

These are the outlet safety plugs I mentioned: https://www.amazon.com/Electrical-Protector-Jool-Baby-Products/dp/B072N9XQHM/ref=sr_1_2_sspa?ie=UTF8&qid=1518274262&sr=8-2-spons&keywords=outlet+covers+child+safety&psc=1

I used the Quiet Lines years ago and they worked very well. I finally grew tired of using up so many of the outlets. That’s one of the reasons I like the Uber so much 👍

 This is actually another subject, quieting line noise. I was originally talking about silencing the physical noise of appliances. Be careful! If you open a can of worms you may get worms all over the place. Ha ha

Quieting line noise is something that is coming from P.I. audio group.  I have prototypes going out.  Small modules like you suggest are great for local noise reduction... especially on fridges and computers.

Dave,
How will this “device” be implemented, what does it do and how does it look?

 And the most important question of all, besides how well does it work, how much will it cost?

It will just be another of my ugly black boxes with an 18" umbilical that gets plugged into a receptacle that is on the opposite branch circuit (phase to some) in just about any receptacle in the house.

It helps to kill noise on that branch which means lower noise on the Neutral as well as Ground that is common on the overall personal grid. 

Still testing, but feedback is very positive right now.

Great questions, Gary.

Works good  :lol:  as the jury says.  Price is TBD depending on what the ultimate part consist is and those component costs.  Tentative price is ~ $500.00, but I'm looking for lower cost, more readily accessible parts and pieces.

I'll keep everyone up to speed.  Rollo will have one of the final prototypes soon.  You can ask him.  Me, I'll say that it is the greatest thing since beer  :beer:

OK Gary bought the wood dowels installed them under Rethm Saadhana speakers. You are correct it makes a slight but noticeable
effect.
Bass tightened and just have better focus and imaging. Well worth the mere investment. Thanks for suggesting. If one turns off all electric devices and unplugs those nasty wall wart chargers and shit it sounds so much better. Quiet is bliss.
So quite in fact you can hear the crickets pissing on the cotton. :lol:

 Hi Charles,

You’re very welcome. I’m glad that it helps. A few questions,
What diameter dowel did you get?
How did you align the rollers? So that the speakers can roll toward you and away from you? (This is the way it is supposed to be done) 
How wide are the speakers?
How long are the dowels you used?
And are they rolling on the floor or carpeting?

 The devil is in the details!

Gary

Gary 7/8" dowels 2ft long. Speaker is approx 10" wide. Set dowels front and back perpendicular to sides. Speakers can move front to back.
Thanks Dave will be expecting a package, oh my !

Would putting the dowls between the speaker spikes be enough to allow movement.
Thinking about putting some on the inside of the spikes and use the spikes to keep
the speaker from rolling too much. Hard wood flooring and what wood for dowls?

Thanks
Don

 I would suggest at least 1 inch in diameter for speakers, and the rollers not wider than the base of the speaker. Only saying that because that’s the way I do it and it seems to work well.  And it’s cheap enough you can try different sizes to see what works well for your speakers.

 I don’t see why not using them between the spikes. But again, not wider than the speaker itself. And at least 1 inch in diameter.

 Sorry, that should be at least 1 inch diameter for the rollers and not longer than the width of the speaker.

We used putty to limit the dowels when Gary was over at my place, but the putty was messy and I wouldn’t use it again. I’m sure there are easier methods, but I have yet to experiment
