Out of interest, I contacted Power Inspired about the current delivery of the AG1500 and it is rated at 6A continuous and 12A momentary. Is this enough for good dynamics in a HiFi system? 1.5kW continuous is typical of a good regenerator and will suffice for all but giant class A amps. Momentary is moot, remembering that 13A supplies set an upper limit of around 3.5kW or so. |

Thanks.
I have a 16A supply (no limiting plug fuses) but I am sure my amp requires a lot less than that.
So in theory, the AG1500 would suffice and in not likely to flatten the sound stage or dynamics?

I can't speak for the AG1500 but my PS Audio P10, of similar spec, gives astounding dynamics and a good 3D stage.

What benefit would a mains regenerator have over something like a Furman AC210 mains conditioner? (thanks for the tip Jerry).

I don't like mains conditioners in general, they tend to filter the life out of the music (literally). Filters are passive, they filter out noise but cannot reconstruct a distorted waveform. A regenerator actively reconstructs the waveform. Different principles. I can't comment on the Furman.

He was probably out of phase compared to surrounding properties, as they are normally grouped in phases. Still not with it yet. Still trying to adapt to funny French mains. My french electrician has just confirmed the EDF NEVER supply an earth connection, so all installations are TT. ... Hi Richard I've not done anything to my supply yet (am planning to in the future), but wonder whether you might get the best return in the mains area from improving your earthing set-up, which is clearly an option due to your TT installation. I'm assuming your kit is not double insulated and makes use of the mains earth line. Have you put much thought into this? Cheers. Bill |

Bill Hi Bill I haven't considered any earth improvements for HiFi noise reasons. I have no reason to think that significant ground noise is coupled into the signal on my equipment, and have no expectation that mains tinkering will change the sound. I am a bit anxious about the quality of the earth rod for safety issues, and have booked the electricians to retest because we have covered the ground with a patio. Of course, it has poured down heavily for 4 days, which slightly undermines that safety test, and I will redo it again regardless at a barren dry spell next spring. However, providing the impedance is safe (100 ohms here in France) that is my only concern. I doubt very much, even with the best spikes here in wet conditions that we could get that impedance much below 10 ohms. But noise on ground lines does not bleed away to true earth. Noise is AC. French radial circuits already amount to a "star ground" system for the building, which is about as good as it can get - and far more important to any noise issues than the nature of the connection to true earth for fault protection safety reasons. Because I know that folk on this forum are going to keep tinkering with mains as a hobby parallel to their interest in music, I won't labour the point, but I will just finish with one of my favourite quotes on the subject of noise "bleeding down a low impedance path to true earth" - this is from Bill Whitlock of Jensen (this one should appeal to Wonky) "Are EARTH grounds necessary to prevent noise? Think about all the electronics in an airplane!" Have fun with your projects. Best wishes Richard |

Hi Richard
I used to do a lot of audio work on fast jets - I certainly would not class any of the signals as low in terms of electrical noise!
Cheers. Bill
