PS Audio Power Planet Regenerator? worth it??

Mains regenerators will convert the incoming AC to DC and then invert it back to AC and also reset the sine wave. Most mains supplies are not perfect as regards a stable voltage or a true sine wave but virtually all hifi products are designed and voiced using the normal mains supply so if you place regen in circuit then it's likely it will sound different.

Hi,

I looked up the requirements for mains supply distortion, and it is allowed to be quite high :

https://electricalapprentice.co.uk/harmonics-standards-what-are-they-and-how-can-you-use-them/

It allows for single digit THD.

I ran a simulation for a 10ohm load on a 50volt output of a secondary winding of a transformer, and the result for a 10,000uF reservoir capacitor current. The current to sustain the charge within the capacitor is very high.

The peaks are at 54amps.

If we examine the harmonic content of the charging current for the capacitor, then :

The harmonics are the same as the 100Hz switching frequency of the diodes in the bridge rectifier. The number of harmonics and their magnitude from the diodes far exceed any harmonics that may be present on the mains supply. This would mean that a regenerator with 0.3% THD although lower than what is possible on the mains, is still at the same frequencies that the mains can produce. There may also be periods where the THD from the mains is near zero, so the regenerator is dominant as a noise source on the mains.

In addition to this, many tests show that competently designed equipment does not suffer from mains THD, or power supply noise such as harmonics from the diodes switching in the power supply.

Shadders.

There may be an issue here, because published measurements will most likely not be taken using raw mains.

There's no reason not to use the mains direct. The performance will be the same.

That's just it, it won't sound different because amplifiers run on DC. There is no such thing as mains voicing.

Well every regenerator I have tried certainly altered the sound of my system 😟

Hmmm ... so does that mean your system won't sound 'right' unless your mains has exactly the same deficiencies as does the mains at the designer's premises?

Hi,

That is too logical.

The logic i think about the mains regenerator is that all the bad stuff on the mains is stopped by the main regenerator, and it outputs 240volts RMS 50Hz (UK) with at most 0.3% THD.

So, the regenerator converts the mains AC to DC, and then back to AC (as per other poster).

So, the mains AC to DC conversion must be very special to stop all that bad mains, and not be affected by it, else the DC to AC conversion will mess up.

So, why don't manufacturers make their AC to DC conversion just as good as the regenerators ?.

I think every f*cking manufacturer in the world must have their AC to DC conversion wrong, and only a specialist audio manufacturer can get it right.

Regards,

Shadders.

No!! 

A regen producing company is spending ALL the production budget on the regen circuit. The other audio manufacturers have to spread the budget across all the functions of the unit they're producing, hence the difference in the performance of ac/dc sections. 

£££ is the difference between adequate & exemplary in most things, not just audio.

You tell 'im John.

I still cant work out how come all these clever people haven't got top jobs designing audio equipment bearing in mind their claimed superior expertise.

Hi,

It does not pay as well as more professional disciplines.

That’s a fair point. 
 

What other better paying discipline have you found for yourself?

Yay, one of the best technical videos ever and so good I actually bought one based on the technical and scientific arguments in the video (even though the video had not been made when I bought it!!)  . . . . . . . . . . . and then I sold it and bought one made by one of his competitors in the UK . . . . . . . . . . . and then I sold that as well and now I have better sound quality than with either.

Hey ho, well we are all allowed to make mistakes.
