Years ago Hi-Fi World did a feature on using an industrial motor as a generator.

I have recently done at least 2 major mains changes for my HiFi. A couple of years back , during a 4 day power cut over Christmas, I completely replaced the National Grid with a 3KVA generator lent by my ex-wifes new boyfriend and heard no difference. More recently I have replaced the UK national grid with the French national grid, and can report the same observed benefits as with the switch to the 3kva generator. Like the Japanese gentleman and his pole, I of course, have not carried out a series of A:B's to confirm my findings. I wonder if he does that when he buys a new cartridge - buys it on spec and concludes its much better than his last gramophone needle. Or whether, for a cartridge, he feels it appropriate to visit a shop, and have the hapless salesman swap back and forth half a dozen times (guilty as charged on that one, personally) However - don't laugh - I have just paid to have Cat 6 cable run up through the loft and out through a trench to my new garden office, so I can remove the homeplugs and still have ethernet instead of wifi. I am not expecting any diference when I unplug the home plugs (I evaluated the effect of the UK variety plugged in and out back in blighty) - but clearly the brainwashing has had an influence over the years

The principle is sound - tap your power into a lower impedance point, which is all he is doing by having his own pole and avoiding the distributed feed to the neighbours. A tad over the top as a solution, though

A/B testing of poles - the mind boggles! However - don't laugh - I have just paid to have Cat 6 cable run up through the loft and out through a trench to my new garden office, so I can remove the homeplugs and still have ethernet instead of wifi. I'm not laughing. I do everything I can to avoid hash on my mains and home plugs are a definite a no-no. Keep your power clean, use ethernet - yep, it's a way of life!

Yes indeed and people have spent money on worse things.

If I had that sort of money, personally I would have other uses for it, but the same could be said of donating it to casino owners. Not my idea of value but if that's what lights up your life.

Be careful Richard you slowly moving to the dark side of the force . The force is with me I won't pretend to be cool, and that I wasn't influenced by mains noise ideas, but they weren't the main driver. I even told the electrician fitting it about keeping the mains pure, and he gave me a funny look. As a result of which I tried removing the home plugs again and got the same results as in the UK - namely none. (The test in the UK was a bit more rigourous - I used a very reliable set of ears which have recently been put at my disposal - Sues - and did it completely blind. She didn't even know what I was testing. And I stuffed traffic down the wire.) However, I need several ethernet points - a VOIP business phone, my PC, Sue's PC, the TV boxes, and the Raspberry Pi. The UK homeplugs were flaky across circuits on the consumer unit, although the french ones have been bomb-proof so far. But they caution against using more than 4 of them on the same ethernet network My noise issues, have always been noise on the signal, from mains or elsewhere, rather than the mains itself being in some way noisy or inferior. The noise issues here are going to be the 10m HDMI cable to the projector, and 10m connections between AV front L&R from the AV amp to the PIP inputs. Wireless is an option for the projector, but the installer is confident HDMI will be fine at 10m. I have a high quality transformer to break the earth loop on the audio connection, which will remove any hum issues, but I may look at making that connection fully balanced, since the environment is full of HF gunk (my UK and french mobile, sues personal and business mobile, a tablet each, and a laptop each, all on wifi as well as the 4G) At least we get decent broadband speed here, 6 miles up a mountain, with a population of 89 - 6 miles from the nearest small town. On copper. And earlier in the year they were digging up the road to install fibre optic - to each house!!!! Due to be connected before 2017.

mains quality is very important for audio balanced transformer or just make your own electricity with solar or wind " the sun never sends you a bill "

The villa we stayed at in the Dordogne had a promising looking Orange Live box, presumably some kind of broadband service down the telephone line? We found it laggy and pretty slow most of the time.

We have a few clients which use solar power only for the audio, certainly has a positive effect, not sure it's quite right but they are happy
IMHO mains quality is up there with room/speaker interface and amplifier / speaker impedance matching
They are many ways if skinning a cat

The Livebox supplies the internet. It's efficacy depends on the broadband signal. A lot of rural areas suffer poor broadband speed for a variety of reasons (contention, currently where I am - hopefully a non-issue after they connect the glass). Quite a few rural broadband supplies are via a satelite dish for the village and these can get real slow. Once you have a livebox your "normal" phone landline is in fact a VOIP service and the landline no longer carries audio signals. Except at about 3PM when the kids come out of school, I get pretty good speeds here (9Mbps down, 1 Mbps up) and the phone is just "normal". I have my own UK business VOIP phone also using the facility Fibre optic will be awesome hopefully

I trust it will be particularly smooth operating. I assume your clients have a battery in the installation so they can listen at night, just as we will have a battery so we can open the gates on cloudy days

Like to hear or anyone who has tested out solar or similar, battery as well I assume for consistency

Let's hope he disconnects all equipment in his house that use SMPS, otherwise his investment in a personal distribution transformer is somewhat wasted.

.... just make your own electricity with solar or wind " the sun never sends you a bill " But the sun doesn't always shine, nor the wind blow. And where do I put all those accumulators, so I can listen to my system after dark?
