I am not sure about spending £8000 on the PS Audio Power Plant p15, after all it is an amplifier in reverse and I do not think it justifies the price. I already have an Isotek evo genesis one to run the source components. What do you think?
I agree with you, it’s not needed.

Er, don’t buy it then?

Donate the money to my speaker upgrade fund

Those were ideeply discounted and cleared out in the United States. Price drop from $8K to $4K. P12, P20, and the Stellar Regenerator are stocked.
I thought about it,. I have a 2019 P12 (smaller version) that does the job just fine. But I did buy new speakers….

But I want a perfect sign wave!

All devices plugged into such heavy blocks of something have their own PSUs with their own power “sine waves”. So, you won’t get that “perfect sine wave” into whatever device plugged in, anyway.
And that kind of power sine wave has nothing to do with the analog audio sine wave an audio device produces attached to such a block.
This has been explained numerous times.
Only exception might be if your power grid or some analogue audio gear’s internal PSU is extremely bad running beyond any given standard.
And, as with all additional devices in the whole audio chain, they increase the likelihood of additional/new problems. Read here just one example from real experience… Barely audible hum from P15 - Power Components - PS Audio.
So, for such a big amount of money I’d spend it on a travel to a foreign country 
. It would be much more real and can offer great relaxation and learning as well

Or, for a realistic sound improvement project, invest in room acoustics treatments and/or better speakers.

The value of these devices has been shown to be negative (money wasted, more heat, more energy loss, etc.):

The PS Audio Power Plants do a good job regulating voltage and removing line noise. I wont make any assertions as to improving sound quality.
I attribute that to premium quality equipment.

Which means it’s useless for audio devices.

Marian, unless you are a qualified engineer from a reputable audio company, I’m not interested in debating it with you. You do you.
You can read the reviews and see that the PS 12 unit actually increases the noise floor over the household mains though it does reduce some of the harmonics meaning the sine wave is a bit more sine-wavey than the mains power. You can also read that it is not impactful on the performance of the audio devices.

I’m happy with it. Some reviewers like it, some don’t.

Why? You would rather not hear that!
More to the point, power supplies in audio equipment are largely fine with “dirty”* AC, and manage to provide perfectly regulated DC for your amplifier and DAC. That’s where it counts.
*Mains AC is governed by regulatory standards, and power supplies also have to meet such standards, which are designed to accommodate the afore mentioned regulations.

I’m not debating anyone, I’m just drawing the logical conclusion from your own post. No qualifications needed for that.

You can of course find voltage regulators 20x-30x times cheaper than that thing.

Buy a Network Acoustics Muon Pro network filter instead.
