On Audiogon, I have found a lot of excellent advice and great people so I thought I'd say thanks to all and give a little back. There is so much information in the forums on power, grounding, electro magnetic interference (EMI) issues, noise and various cable dynamics such as impedance and signal reflection. The only problem I had is finding it in the forums and then finding more technical information to explain deeper why the advice works.
If others agree, I would like to start a permanent thread of technical sources and references links, but not specific advice like the forums.
An excellent source I have found, (with references!) is by Philip Giddings at: http://www.engineeringharmonics.com/papers/papers.htm
I placed relevant links below with comments, mostly from the author's text (with a few from me).Grounding and Shielding for Sound and Video
(This is it: The *must* read, you'll need coffee!)
Power and Ground Update
Balanced Power - The Final Frontier? (A cutting edge discussion of balanced, isolated ground systems in studios.) This article provides some recent ideas and developments that affect electrical noise in audio and other technical systems. Anyone planning a new facility or a renovation will want to consider how these can best be used to maximize and protect their investment.
Noise Reduction Systems
This article discusses a number of established, well known single-ended noise reduction products.
Grounding Systems and Their Implementation
(Excellent for home wiring) This paper discusses the grounding system installed in the facility up to but not including the electronic equipment as implemented in a number of large installations and is part of an on-going AES effort to document appropriate practices with regard to the control of noise in audio systems.
Getting a Perspective on Noise In Audio System
(Excellent overview) This article provides background on where, when and why electromagnetic interference (EMI) noise enters audio systems.
