Electricity Tuning

Bert,I do not use these in my 2 channel room(Naim gear),but a couple of years ago I re -did the walls,and all the wiring in my home theatre,I had 5 dedicated 20 amp lines installed for all the electronics.For wall outlets,I used Synergistic Research Tesla Plex Receptacles and to cover the outlets,I used Furutech outlet covers 104d...the results were quite good for my home theatre,I have considered installing them for 2 channel also,but have not got around to it yet.

Bert, I use a Russ Andrews Mini Purifier on my mains distribution close to my hifi. It is effectively a inductorless passive differential and common mode filter and seems to work well and reducing high frequency ripples on the mains... for me it makes a small but worthwhile difference... not a lot of money either. Cleaning up the mains doesn't need to be complicated or expensive...

I had a dedicated line installed into my room with 20 amp cable and socket. It was installed into the fuse box with an RCD switch which has since had another RCD installed for a new washer/dryer combo on a double RCD socket (sorry I don't know the correct language) Apparently they don't share the incoming line, HOWEVER I have no doubt anymore that when the washing machine is on the sound quite obviously loses PRaT. I have learned much about hifi, power and acoustics in the last couple of years and ALL of it the hard way! My opinion if it helps, over engineer. Do everything as though you are installing amps with 2000 watts, large diameter cable, high quality sockets, Very good grounds earth! and only dedicated lines from the pole to the wall as best as is possible. Don't be pushed into second best by your electrician! I have learned that run of the mill house sparkies don't grasp the uniqueness and sensitivity of audio, ask around first and check if he is familiar with that, highlight the need for high amperage circuits WITH very good grounding.  I have gained valuable knowledge from members here on this stuff, just ensure you always take the advice of the electrician in the end for safety and insurance.

That's funny,when I told my electrician I wanted 5 separate lines running from my fusepanel to the wall behind my audio rack,he thought I was nuts.I simply said ,that is what I want you to do,can you?He reluctantly said sure I can,but why?

I don't understand so much the technology aspect. But the plug I am testing right now seems to correct phase mistakes by adding the opposite phase mistakes......, whatever it does, it works in my ears. They come in plug format or in complete electricity system in which you can plug your Naim electricity plugs, seriously considering the royal solution....

Not quite sure I see how it can 'correct phase mistakes'.. if you have single phase mains like most of us, the phase is the phase....doesn't matter how many degrees offset it it to other phases elsewhere in your neighbourhood... I suspect however it's a passive noise filter of some sort... and if it is helping your Naim then great...

Hi Simon,

I guess you are right and i have misunderstood how it works. While I am an IT Guy I am no electrical engineer. But what my ear recognizes is that it works. In case I will allow myself the Royal solution I will make some pictures and try to get a more precise description for the benefit of other forum members.

Bert,  perhaps you need to explain what you have by a link or copy/paste the makers description to help us understand what you have.  Your domestic supply is single (or one) phase,  230v Live (or Line) & 0v Neutral    

Moderated Post:  Mike, Bert, no commercial links in the Hifi Corner please, thanks.

Mike like mentioned before I will publish my solution if I decide to go for the royal solution. Right now it would be quite an effort to get the plug out, it's completely behind the audio system, and I would hate to negatively affect cable dressing...

Bert OK, geen problemen en kunt u geen behoefte aan als het een hoop problemen.   Re Richard's moderation request for no links,  I had in mind a circuit or picture,  not so much a product brochure link.    Please understand I fully understand this kind of description problem, it's an extra interest for me as I used to be responsible for technician training in various languages at our schools in Brussels, Prague, Barcelona & Moscow.  We frequently found words in common use within a 'trade' to be incorrect in translation.  We recognised the common meaning of the word rather than the translation.  It was a particular challenge for our 3rd party translation cmpy's & we had to compile an index to manage this.

A few new products have been stirring a fuss lately,   Devices that supply a clean ground for the mains AC supply. These connect to a component such as a dac or connect to a mains distribution block or wall sockets that have an earth point.       Most are pricey and all inclusive within a brand.  I haven't seen a low cost plug in of this type yet to try.

Hi Bert,

assuming the usual situation, your power supply should be like this:

Three Phases, each one carrying 230 V, with a 120° lag between them (L1-3) and a single Earth/Neutral (PEN) wire entering the house. The PEN is split into (Safety-)Earth=PE and Neutral=N immediately after entering the building. This is called TN-C-S, if you live in on of the few regions featuring a so called TT-System (not the one from Audi ), things will be a little different. Best to ask your local provider about this.

Mike:

is this something you can use?

Mulberry, perhaps  Dutch houses typically have three phases delivered to them - I know most in the UK don't. But if one was using multiple phases  to say provide a single split phase supply - the voltage would be 415 volts and not 240 volts --- not really that much use for Naim equipment or most domestic equipment - but useful perhaps for the workshop...

I think Mike was referring to the filter being used as opposed to the electrical supply and its earthing configuration..

Hi Simon,

the three phase supply is what we have here in Germany, where Bert (according to his profile) and I live. The spurs are supposed to be equally divided among the three phases (for a house with a total of thirty, ten on each phase). Only the biggest units, like ovens , power tools and some disc washers use all three in a so called "Drehstrom" configuration with 360 V.

Mulberry,  I'm an electrical engineer & am certainly not looking for solutions, but thanks anyway.  My post was trying to understand what Bert is describing so as to better understand his problem,  I then went on to explain I understand the confusion with translating some technical terms in common use,  & although I didn't say as much I haven't heard the word or its translation of 'phase' being misunderstood.

Hi Mulberry - indeed Germany does provide typically three phases to houses - but i think you'll find most of the supply is at 220 volts yes? So that is a single phase - and you may well find your house is separately split across the three phases no? 

Bert's point was about his filter - and he felt it was 'correcting' phases - well if you changed the angle between two phases then it would only be meaningful to my mind if used to supply a common load such as a  split phase supply - which if a single phase was 220 volts the two phase split phase supply would have a maximum of approx 380 volts .... which I don't think is what Bert was referring to...

Hi Mike,

I have re-read Berts post and think that I had misread it the first time. He seems to have some noise-canceling device, like the earphones of that type. My original impression was that he had one th check the phase/neutral polarity of his equipment or power strip.

I will wait for Bert to get back & see if I can understand better.

Hi Simon,

yes, the supply is usually a single phase at 230 V and the whole house split among the three phases. The three phases, if used together "add" to ca. 400 V.

 The 360 V in my previous post we're a typo, for the "old " 220 V, the three phases gave a total of 380 V.

Guys made a picture and was able to also find the way it's working. To not violate the rules of the forum I will not mention the brand name or use links to the website....below you find the description...

work in parallel to the mains feed by adding countersignals to detected noise. This is unlike most other power conditioners, where noise-suppressing elements are located in the power line, between the outlet and the electronic components. This restrains the amount of instantaneous current the equipment pulls from the mains.

Now with picture...

Looking at their website, it says that they work if plugged into the same mains group. So if you have a dedicated line you'd need to plug it into the dedicated line as well. They certainly look interesting.

Some more information on the effect...

can easily be heard on nearly any audio system. They effectively lower the noise floor and by doing so improves the dynamic headroom in the music. Every note will appear clearer on a darker background. When used in an A/V system you will also see the effect on your screen – better contrast and fewer grains.

But that's just marketing puff, surely. 

OK Bert  I have it, thanks.  I've found the www, read & understand the technology.    If the end result sounds good to you = great, enjoy.  I will have a more in depth study tomorrow
