Wall outlets

@mc1969 , electricity has no sound. But the stuff you plug into it sure does. The goal here is not create a simple circuit, but to get the most out of your equipment. 

I don't see your system listed, so perhaps a simple $.89 Leviton outlet from Home Depot is more than adequate for your particular setup.

However, once you reach a certain level of equipment, it's fairly obvious that cables, connections, connectors, power conditioners etc... all make a difference. 

Good luck on your journey and happy listening.

As a retired Biomedical Equipment Technician I understand a little about electricity and electronics . As an ever improving DIY type audiophile I heard a difference , I'm not sure what your point you're trying to make ?

But thanks for repeating yourself about " electricity has no sound " , if you can't hear a difference then you've stated your opinion you can't hear it .

It cost nothing...I was lucky all that was already done in my new smaller house...

I was in the obligation to sell my larger house...

My system there was connected to a secondary electrical grid on the second floor..

The sound quality was impacted negatively, but i never realize this ...

I had been conscious of this only on my new house...

My audio system is near the  main electrcal panel in the basement...The improvement was noticeable at the first minute of listening...

I will change the wall plug and all will be done for the best...

Another great improvement was using a small battery dac... No connection to the grid or my computer at all... Save the amplifier on the direct main panel line ...

@mahgister how much was it to do that ? 

Keep telling yourself that 😂 @coralkong  my system is as or more revealing than yours. Have 5 dedicated lines, and all those outlets are still in place. The .99 cent outlet is what I plug my laptop into. 

So when you go to a audio show they replace all the outlet in that hotel room? If it really made a difference they would, but they do not.

You have been bit by the Snake Oil Salesmen and so was I. I did my experiment and found ZERO benefit, Also same with the vaunted cable lifters. Now I do use quality cables (Synergistic, DH Labs, Transparent, LossLess) I also use quality power distributors  ( IsoTek and Wisdom Cable). I have Puron (4) and NFC Power (4) filters as well and they made a substantial improvement as they actually have filtration qualities unlike a $200.00 outlet that simply provides a ground. Also have the Puritan Ground Master (made minimal difference as we upgraded our whole house ground when upgrading our dedicated lines),.

My journey is complete and I am enjoying Piano Concerto No 18 in B-Flat by Vladimir Ashkenazy and it is giving me goose bumps. I am sure it becasue of the Cardas Duplex that my SPL m1000s are plugged into. 

@vair68robert one more time "electricity has no sound" it may transfer noise.
