This is a project that has been on the cards for a long time. Fair chunks of the spur (or all of it) will have to be routed around the outside of the house, which has kind of stopped me at this point (significant WAF barrier). There is a good series of articles by Ben Duncan on this - his Superspur series. He has this rebound as AQMS (Audio Quality Mains Supplies). Also has articles from the pro audio press on wiring up recording studios with high quality mains. Hi Craig I've been wondering about getting a copy of this - have you learnt much from it? Cheers. Bill Somewhat. Ben's writing style is sometimes a little odd to get to grips with, but he has been around the block a time or two with mains (spurs, balanced mains, pro and domestic audio etc). The only quirk is he recommends an earth wire called Radex which costs a fortune (a fiver or more a metre). Allegedly Radex stands for Radio Exterminator, although what stranded copper wire in a sheath can particularly do for RFI leaves me a bit puzzled. Particularly as a spur regular steel armoured cable is recommended. Anyway, AQMS is listed here for £22 store.securehosting.com/stores/sh204131/shophome.php?itemprcd=aqmsbd . |

Hi Bill have you read any of what Rory K riches has written he has researched the mains effect on hi-fi for years and written many articles which I could send you. He used to be around on the forums quite a lot but he has laid them down about five years ago. He lives about an hour away from me he popped around to my house about three years back and gave me some excellent advice. I'd be interested in those too! |

He lives about an hour away from me he popped around to my house about three years back and gave me some excellent advice. Hi James Yes, Roy sent me his pack of data a few weeks ago - one of the things he did was to test 6 or 8 different consumer units, however I understand that his recommended MEM unit has been superceded by something much cheaper to make! So I'm not sure which to use yet, some recommend Hager, but I don't know if this is based on test results. His recommended route is to use multiple radials, preferably straight through to the IEC connector on each run with no switching or fusing apart from at the consumer unit. I'm thinking more of a large 16 or possibly 25 mm2 radial that would feed a big balanced transformer, something similar to your Mother Trucker, with suitable circuit protection. I suppose that an alternative would be multiple radials to multiple BMU's, one for each component - but I've not come across anyone who has done this yet to know if it's worthwhile! Cheers. Bill |

Interesting to note that Roy doesn't think balanced mains is a good thing.... I too benefitted from his research, very generous man. Though I disagree on the use of balanced mains  |

I wonder if multiple radials is somehow better for the kit.... I had been thinking of just one radial for the kit before |

Hen Roy came to my house we had a long chat about balanced mains, he doesn't disagree with balancd mains but all that he has seen has been poorly designed and that's what he disagrees with as it puts noise onto the system. I've got to go as we have people coming for dinner but I'll further explain this point later on tonight |

Hi Mike
I guess with the regenerator you're in a similar situation to the one I have planned using a large balanced transformer - unless you're planning on multiple P10's of course! That's why I'm considering a single large cross section cable for the radial.
Cheers. Bill

Multiple P10s. Hmmm. Lottery win and new house first |

Though I disagree on the use of balanced mains As I said all the balanced mains RKR has heard hum / rattle like mad. Even Ben Duncans BPS hum so bad I can hear it in another room, and he is the 'world authority' on mains. I wont name any more BPS manufacturers here but they all rattle. If they dont they either use a DC blocker or the tranny is heavily doped to quieten it down, which works. And thats what Roy struggles with, even though these designs still have a great audio benefit. However the Tranny I use is silent, completely silent. It is silent due to excellent design, not my design I must add, and the design is everything. No DC blockers, no doping. And its a whopper at 3/5kVa. As Roy Riches is only an hour away maybe I should schwing by and see what he thinks of my MTBPS |

Be dead interested to hear balanced against a P10

Come round Mike with your P 10 you're not too far away from me

I was hoping for the balanced to come to me Have you seen the weight and size of a P10 ? To be safe it's a 2 man lift |

Have you seen the weights and the size of the MTBPS?

Post by MikeMusic on Feb 5, 2015 15:48:51 GMT
Ah no. I think I have seen a picture of another - or maybe misjudged the scale of that How does it compare to the P10 ? 43cm W x 36cm D x 21.5 cm H 33k - feels heavier than that, but I am positioning it on a glass shelf sitting on steel spikes into a Mana rack Last time it went in there were 3 of us |

The P10 is a bloody heavy lift - as much as I can manage for a short distance. That's 33kg, Mike, you left out the all-important SI unit!

The MTBPS is 450w x 400D x 220 high weighs in at about 35kg ish

Sounds heavier then |
