Can I say I've never doubted the value of the BMU as I know RD operates on a comparatively low margin. I also knew that the cases were very expensive. Mind you. I was still shocked at the price of the sockets.
Where I challenged market prices were in terms of transformers for this purpose seemingly costing exponentially more. Also where a Balanced mains device seems to have little more than a transformer, a cheap case and a pretty standard mains socket. If 1kva transformers for the purpose can be had for £76 then I feel that the vast majority are overpriced.

Therein lies the difference between buying directly from the manufacturer and being on the end of a chain.

To express extreme caution to an amateur dabbling in home brewed mains equipment is not paranoia. Anyone considering doing it should take a close look at their ability and knowledge and think long and hard about whether they are competent to construct something that won't put themself or others in danger. No matter what the potential gains to sound quality that balanced mains might bring, I promise you that your hifi will sound crap from the inside of a wooden box buried six feet down.  funny but true. |

Some understanding of a) R&D recovery, b) actual manufacturing costs, c) parts costs, d) safety testing & certification, e) fixed and variable business costs and f) profit margin are required here. It actually makes the NVA BMU look remarkably good value for money when you cost everything in. Please don't be looking at the price of a toroid on eBay of questionable origin and quality and be building a picture in your head of how much the finished item should be selling for unless you can account for all of the above. Yes this is what I have thought all along. There have been some misguided comments made especially regarding tax and VAT in this thread. I have never been employed, I have always run businesses and even a simple one man band has to pay considerable costs to run his business. I still believe £500 for a very smart looking NVA BMU is good value. This also comes with huge backup should anything go wrong. |

How does a Power Inspired AG1500 mains regenerator stack up to the alternatives?

The AG500 which I had does things differently . The improvements it provides are more subtle . I've heard both and if I was going down this road today it would have to be the BPS which seems to provide a more fundamental and obvious improvement in SQ .

That is interesting Brian.
I have a small amount of DC periodically on my mains, so I am thinking that a future upgrade could be worthwhile.
The DC blocker I have has pretty much solved the issue of a noisy transformer, but I am wondering what benefits a mains treatment of some kind could potentially have.

This is a '' suck it and see '' kind of upgrade Kevin . Everyones power supply varies in quality unfortunately . I'm not sure what the quality is like where you are . However , I would say that there is a 60/40 chance that the BPS would provide a major improvement and a 70/30 chance that it would provide a worthwhile one . When Ali plugged his BPS into Garys system a few jaws dropped .
I'm not sure if it would fix DC or a noisy transformer but I'm sure one of the experts will be along to provide information on this .

Not so the PS Audio P10, which had both a similar 'structural' authority to the sound and also the detail and microdynamics that the BMU missed. It's not a fair comparison as the prices are an order of magnitude apart, but I would not be without my P10. |

And there is the subterranean bass the P10 has

I Used to run both on AG 1500 and a balanced of power supply together, though that was quite awhile ago and my memory is a bit shaky but from what I can remember the AG1500 brought more air and space between the instruments with a nice level of extra detail and musical projection. The balanced of power supply on the other hand brought more welly and authority, improved baselines, tonal character of instruments, detail and ambience. In the end I was a bit strapped for cash so I sold my regenerator and just stuck with my mother trucker balanced power supply , however when I ran them both together they definitely each gave a bit of their own upgrade characteristics however I have to admit I'm very happy with just the balanced power that I have now , maybe one day I can put P10 regenerater in my system for comparison; that would be very interesting .

With John, Colin, Martin, Mike and Steve so close and me in Maidstone, we should have a TAS day,
I'm completely off the grid until maybe September but we should organise something.

I have space and a spare room we could put a second set up in to refer back and forth I'll have been retired for a few months by then so might be bored |
