I agree that funding the socket closest to the distribution board is a must or have a dedicated consumer unit fitted just for your hifi. And yes mains filters etc make more difference than cables. Some so called quality cables do not warrant their price and some do. Thats where the people at What hifi and other magazines come in + your own ears.

I personally like the sound when using Russ Andrews mains leads with their RF canceling weave. I find the audio becomes less aggressive with better resonance to bass etc,the sound somehow becomes slower (even though it is not)

Also with regards to quality mains extensions, these are designed to extend the socket in your wall with hopefully no losses. Where the cheapo ones really do degrade as the contacts are very poor.

Give the Russ andrews leads a try on a 30day money back trial and see what you think.

[quote]OK, what effect do the noise and spikes have on audio? [/quote]

Mains noise give you that 'HIFI' sound. That hard edged sound that becomes fatiguing, it robs the audio of delicate treble and certainly robs it of natural resonance in the bass. Vocals become smoother and less ear grating with good leads and filters. Bass is more one note too thanks to noise.

Mains noise and short duration spikes of the sort you are talking about are crushed to oblivion in the PSU of any amplifier and one note bass effects can only be caused by poor speakers. Even my mains radio has no interference which it surely would pick up if there was a problem. You are talking about a cure for a disease that doesn't exist.

Maybe you 'Think' it sounds really good. You know it maybe all in 'your head' also.

Your radio will not have interference, its purely created at audio level not signal level. I really think you should go away and read about electronic circuits and what effects different noise etc has on different circuit for the benefit of the forum

With regards to my own system running with or without mains filtration it is obvious to anyone that hears it which sounds better and I don't think my ATC speakers are poor at all.

I bet it sounds poop!  Grainy, thuddy, with no air or dynamic range.  This is the sound you have when you ignore the needs of proper supports, mains treatment and connections.  One day your ears will be opened, if they're not full of wax.

Thank you for your wonderful intresting and helpful advice

Please keep it up

Oh dear, the classic "it's heavy so it's scientific" approach.  Try a bit more reading and a bit less flaming please.

Because you've repeatedly broken most of the house rules of this forum, and by asking why you keep being banned you've a) confirmed you are who we thought you are and b) broken another rule: "members must not question the decision of the site's moderators to edit or remove posts or profiles, or begin a discussion in any forum about such actions."

This really has become very tiresome, and we're all wasting a lot of time pandering to your ego, when we could be using that time to help other readers with their problems. Please desist.

One thing I never mentioned before was mains impeadance. This has a large effect on the dynamic sound. At work we equipment for testing local loop (mains impeadence) and we can also measure the continuity of wires using a continuity tester (not to be confused with a multimeter).

First of all the mains loop (from socket to sub station and back again) at our building is 0.14 ohms. I then get a standard mains lead and measure each wire (L N E) and they are usually 0.3 - 0.5 ohms per wire.

Thats higher than the impeadence of the local loop!!!!!

Changing to the test leads I had (Russ Andrews Reference) I tested again over the same 1meter length and the impeadence was 0.00 - 0.01 ohms. Therefore not adding any extra resistance to the mains.

This is where good cables also help

With note to the loop tester the test was carried out @ 26amps and the continuity tester nulls its own leads and tests @ 200mA
