Stellar P3 regenerator first impressions *UPDATED *

Welcome! Yes, a P12 would be better for your situation, but it’s possible a P3 can work in your situation. Someone a few days ago was in a similar situation where there weren’t enough plugs in the PowerPlant to power his whole system. He ended up plugging a simple conditioner into the P12, and then pugged gear into that. He mentioned it definitely sounded better than just plugger those few pieces into the conditioner alone. I try to recommend only having the PowerPlant in the chain, but for the other guy, adding another conditioner worked out.

Hi @audiojerry , is your primaluna dialog integrated and DirectStream DAC both plugged in to SP3? I was also considering it but was not sure if the SP3 would be able to handle that load. I also have Primaluna Dialogue Integrated with EL34 and DirectStream DAC.

It’s a shame these weren’t made to offer the same functionality outside the US. Losing one third of the connections is, to say the least, disappointing.

Yes, sadly I have to agree. Just four outlets (in Europe) makes no sense from a cost/value POV - so I save for a P15 and may never get there…

I think the size of the outlets themselves would mean a complete retooling to a larger chassis to have six outlets on a European version. Rather cost prohibitive I would guess unless the market were much larger.

If only we could shrink the bigger outlets used in other places of the world down to US outlet size.

I would not hesitate to plug a good small power strip into one of a PowerPlant’s outlets to power two things, such as a transport and a DAC. While not as good as a separate outlet for each component, the overall improvement would remain high.

And maybe we in Europe should half the voltage also :wink:

:slight_smile:

There are advantages and disadvantages to each, as with most things. But there is a lot to be said for a higher voltage standard in terms of efficiency.

I similarly found intriguing the industry’s discussion of whether ares should be on a 48V system rather than 12V. Very interesting stuff.

It would be nice for PS Audio to offer a P3 with more outlets for the EU ,etc. but it would need to be offered in a bigger case, negating some of the appeal of a P3. This would also increase the cost.

Regarding the US v European electrical voltage/standards comparison. Remember, the US is a 240V country. I can get a 240V circuit anywhere in my house I need it. 240V operates everything big in the house: A/C, electric heat, range, dryer, etc… sharing a neutral is not illogical either for networked single pole circuits.

Excellent point.

I was assuming EU transmission lines are at higher voltage that in the US, but there is actually no reason to think this.

What gauge wire is used in a 240V house v. a 120V house?

It’s a lot of countries to only get four components. It’s a shame it wasn’t designed to provide the same features to all markets.

The P12 looks even worse - images online seem to show eight components for the US and four for everywhere else?!

A bit open ended. 200A-3/0, 100A-#3, 30A-#10, 20A-#12, 15A-#14. Nothing smaller than 15A in standard circuit breakers.

Oh, and don’t think 120V houses exist. I’ve never seen one.

One last thing, all standard house wire is rated for 600V so it doesn’t matter the voltage use. Works on everything voltage standard including 277/480 buildings.

Sorry, inartful on my part. I am thinking of 120V circuits, not the house as a whole.

It sounds like there is little practical difference between wiring for 120V and 240V.

Nope. Especially if you live in an EMT (Electrical Metallic Tubing - standard elec conduit) house like mine.

Thanks.

I clearly do not know enough to even ask good questions.

Actually, I now own the Premium Pre and Premium amp. I should update my profile, and yes, both are plugged in along with the DS to the SP3, and it sounds great. The SP3 made a great improvement to the system. If you ever think about an upgrade, replacing the Integrated with the Dialogue Premium separates was a wonderful step up. More body, more depth, and serious slam.

Another step up for me was switching from USB to ethernet when I acquired the Ether Regen from Uptone Audio.

Regarding Elk’s question about wiring gauge, here in the UK we tend to have three main wiring sizes within single phase houses (circuits tend to be ring not star): For example in my house:

Lighting circuits - 1.5mm (square) with 6amp breakers
Main Power - 2.5mm with 32amp breakers (this is where we plug in our 13 amp appliances)
Oven/PowerShower - 6mm with minimum of 32 amp breaker

HTH (I’m not an electrician! - sorry I’ve not looked up the equivalent AWG numbers)

I don’t know if @jamesh was referring to me as that “other guy” who put an additional conditioner in the power path, but I’ve done that, of sorts, because of the quantity of source components I have. I plugged my SGCD, two M700s, my phono preamp and my streamer directly into the P3 (with the switch set to regen), and then into the last available receptacle I plugged an old (vintage?) PS Audio Juice Bar, which feeds all of my digital disc-based sources. My thinking was that something as minimally designed and unobtrusive as the Juice Bar might work, especially if all the components connected to it are powered on individually, and never together. And so far it’s worked fine.

For additional context, the P3 is fed from a dedicated circuit that has two PSA duplex wall receptacles on it, one of which feeds an old PSA Ultimate Outlet box that handles the turntable motor and the subwoofer’s amp.

I am just curious, what are pros/cons of using 2 P3s?

Thanks!
