I have plug-in filters and snap chokes all over the house. Reducing mains-borne noise has been vey successful for me over the years. Do they really make a difference with your P10 running your system? It seems odd to me that you would need this with a separate mains feed and the P10. This brings the thread back on topic, as personally I doubt I would notice a difference if you were to remove plug in filters from the mains. |

I come back to PSRR or Power Supply Rejection Ratio. It's a ratio, not an absolute. The P10 makes the components it feeds remarkably free of most mains effects. However, some incoming noise will always get through and a little could even affect the P10's performance itself. The direct answer to your question is, yes they make a difference. I use many to give a good combined effect across the spectrum. There is no doubt in my mind that noise-free mains is one of the key characteristics of a good sounding system. |

Well, someone is not telling the truth.
If it is 100% regenerated, then all the plug in filters cannot make a big difference.
I am not arguing that power is not important, but I have my doubts that the lengths you have gone to are really necessary if the P10 lives up to the manufacturers specifications.
What do the plug in filters do, and how do they absorb the noise on the mains?
I thought that mains filters were supposed to be bad for the dynamics of a system?

Unless the P10 is battery driven then surely mains noise will influence the AC regeneration.....won't it?

If it is 100% regenerated, then why would it?

May I suggest someone’s understanding of regeneration could be wider?

Would that be me?
I am not saying that the P10 is not fir for purpose. If I had the spare cash, I would probably have one on trial as it is likely to be superior to my AG1500.
I just doubt the effectiveness the mains filters will have if the P10 does what it says on the box. It is purely my opinion, as I have never heard the combination, but why would it make a difference to a product that deals with the issues to give you a clean, perfect sinewave?

If mains filtering is so effective to make mains alchemy possible then you barely need regenerated AC....

So there is no point in a regenerator in this case?

I expect it helps but you life is not binary...I suppose it is in terms of life or death. I fully expect the P10 is very helpful but if you expect absolute laboratory perfection you may be disappointed.

Some people are not reading what I wrote. PSRR means nothing is perfect and that some noise will always get in. Let that sink in for a moment.
Secondly, series mains filters have a bad reputation. Parallel (plug-in) filters can only do good. The system's power is not flowing through them at all. The only thing they are doing is removing noise.

Talking about clean power, it's something that had occupied my mind on and off for more than three decades now. And in that time I have not been scared of designing noise reducing circuits into the power supply section of most of my designs. But there are scientific and component availability limitations that have made progress slow. To get a large delivery of energy from the power supply also means that you'll get a large delivery of noise that needs to be brought under control. Controlling noise in a low energy design is a lot easier, which is why I go that route in most things I design. But even existing low energy mains connected designs can get affected by noise that somehow gets through all the noise filtering circuits, which is something that a battery power supply doesn't suffer from. But batteries are not perfect. In the case of rechargeable batteries, they need to be charged and maintained above a certain level of charge in order to avoid other issues.

With the 2nd the effect would be the same, but you'd have the fun and games of getting the cable through them. If its a moulded cable you're knackered. You'd have the same sizing issue as with the 1st ones too - they'd need to be big enough for the job in hand. |

I can't quite believe that all the resident obsessives on here don't already have clip on ferrite beads on their cables.

Good.
I am sat enjoying the fruits of my ferrite clipping activities.
John Mayer's acoustic guitars never sounded so convincing in this room.
