noise on the line


question : power noise & cables : 

- most people agree that in the weeee hours of the morning, with limited power line use and "wifi" / data noise, any stereo sounds better - optimal.  If a vast majority of audiophiles listen during non-midnight/early morning hours why isn't it scientifically acknowledged that audio cables with various shielding theories, intended to eliminate "wifi"/data and power line noise, are valid, not snake oil?!

I've had an H/K A500 and Bose 301's when I was much younger.  Sounded great, Memorable so far. 

But as a working new Dad, ,my best memories were very late listening.

I'm currently listening to Maggie .6

s (OLD) and a Mod Wright / Oppo Pre-dac Streamer through Vinni Rossi Int Amp, and it sounds absolutely wonderful. 

Long Story Short, Power & Shielding & cable geometry make a world of difference. 

Otherwise, why do our stereo's sound best after everyone is gone to bed and turn off all the lights?

No one is saying shielding doesn't work. It is scientifically proven. It's a necessary part of electronics. Systems sounding best late at night is nothing to do with some additional effect of cable shielding.

Objection, the plaintiff is introducing a point of view without evidence. I certainly don’t agree with this statement. I think some systems may suffer from wifi or AC power issues, but I certainly don’t think most.

Having said that I use only shielded interconnects, low noise wall adapters and shielded power cables for my amp to minimize any possible noise effects.

the real story is how much of that noise is from your own house. and fixing your noise issues are most times much, much cheaper than buying an audiophile power conditioner and trying to treat the problems your house is creating.

fix what can be fixed in your power grid, and then you can go from there. but find out what is what about your situation.

a local friend of mine, Rex Hungerford, is a professional electrician and high fidelity home electrical consultant who travels around helping audiophiles optimize their home power. no magical theories or mumbo jumbo, just the facts. he has all the tools, and actually knows how to use them.

you can call him for advice.
