Having recently bought a mains reconditioner, which I did not think would make a difference before I put it into my system, I am interested in knowing which step would be best to tackle next, and where.
My system has the mains regenerator feeding a surge/spike protecting extension cable.
This feeds the system comprising of pre and power amps, cd, TT PSU and headphone amp.
Where should I look at next? A decent extension cable? Upgraded mains cable or the nternal equipment fuses?
I don't have any fuses in my plugs as they are all Schuko.

The first cable to look at is the main feed to the regenerator, as that supplies the entire system.
Then I would look at buying the best distribution extension you can.
Then the individual component power cables.
Finally, the fuse in the main feed cable and regenerator.

Thanks for the quick response. There is no fuse in the main feed.
So cable first, followed by extension block (any recommendations for a Schuko block) followed by component cables and then fuses.

That would be my upgrade order. I'm not sure about Schukos but you could ask David Brook (MCRU) about the IsoTek:  |

I agree with Martin cable to the reginarator first, improve the power chain. With fuses I would also do the reginarator first

Thirded.
I used to think the Regenerator would not need a good cable.
Tested to find myself utterly wrong. Put your very best cable on it

Yes, in Kevin's schukoed-system, I'd change the cable from the wall first.
I must admit I am a bit (no, a lot!) wary of changing internal fuses. But Martin seems happy with the idea and he knows infinitely more about the subject than I do!

Proceed with caution - but most 'internal' fuses these days are rear panel accessible, like the P10 regenerator. Replace with a like-for-like rating and you should be fine.

The following applies if you have a REGENERATOR - Your posting is ambiguous as you also refer to a 'reconditioner' which is not at all the same thing.
For sure take out that surge protection cable and replace it with anything else (In my experience such cables inevitably degrade the sound).
You could take the opportunity, as I did, to use IEC cable/plugs throughout rather than '13 amp' plugs ** - that way you don't have any mains fuses.
** That's assuming your regenerator has inbuilt protection for overload etc..

Thanks for the response. I have a mains cable coming for the AG1500. I will be honest, and state now that I do not believe it will make a difference, but I want to find out for myself and I am open minded enough to try it. I will happily admit I am wrong if that turns out to be the reality.
As mentioned in my post, I don't have any 13A fuses in the plugs as they are all Schuko.

I bet the cable will make difference.
However if it doesn't ..... go looking at other areas to do with the rest of the system.
Every system, room and house I have improved with mains I heard differences. Sometimes dramatic.

Am I being thick here? Surely the purpose of the AG1500 is to provide a stable, pure sinusoidal 230v. Or, to quote their own blurb...
How can what you feed it make a difference? Isn't the clue in the name? Regenerator. Or is the AG1500 so bad at its job it's hyper critical about what you feed it with, rather like me.

This is part of what I want to find out for myself.
How can it make a difference before the generator? If it does nothing there, will it work on my pre or power amp?
Does it make a difference at all, or is it another urban myth?

Perhaps you should regard a regenerator (or any mains doodad) as improving the supply by say x10, or whatever figure you fancy. So the better the input the better the output.
It was certainly my subjective experience that it mattered what you fed my AG1500.

I think its good you going in with a bit skeptism
In my case it has made a noticeable difference. The reginartor does a good job without this but seems to benefit in my system from this. To be honest I rather the unit had a good captive mains I understand why we went down the IEC route but a lot to be said for just having one good coneection

Seems logical on at least one level Makes a real difference though |

Yes, that's what I think is happening, too. Certainly the quality of power, the power cable and the fuse all make a difference to my P10 regenerator. It may seem counter-intuitive, but no component is impervious to what comes before it (and remember, the regenerator's highly accurate oscillator circuit has to run off power rails derived from the mains), so it's all about Rejection Ratio: how much of the original crap can it reject? You can then see how it gets better the cleaner the input power gets. |

So if you want to get the best out of an AG1500 you should really run it off of an AG1500?  |

Why stop at two?
The more the merrier.
I do recall someone running a AG1500 from a balanced power supply gizmo and liking the results - or maybe it was the other way round.

I did try running my P10 from a BMU but I felt that the combination didn't give any benefits over running the P10 alone. However, passive noise filtering (plug-in units) dotted around the place and a good power cable do make a difference, so the P10 is certainly not impervious to the quality of the incoming mains.
