Garth Powell's Stance on Power Regenerators

I zoned out at No. On “limp home” mode after that. Did I miss something important! :roll_eyes:

The Pass Labs XA160.8’s (the "XA line being single-ended class A) are spec’d at a max output of 50 amps at 56 volts, which at 2,800 watts I assume to be peak output. Even the Pass XA 60.8’s (nominally 60 w at 8 ohms) show a maximum amperage spec of 30.

I have another question, this time has to do with PSA regen and PSA gears. Suppose regen clipping above certain Amp, assuming the gear uses amp into the clipping level, But, we know PSA voicing(or tune) its gear with regen, does this tune compensate the clipping?
If so, PSA regen + PSA gear will be the best pairing. Maybe, this is why I seems hear sonic improvement from my PSA gears (M700) with P12.
Thanks.

I’m sorry, but Garth does not appear to understand how power amps work. That 20ms current surge is on the DC rails across the speaker load and never gets to the AC cord due to the caps in the power supply. If It did it would blow the AC fuse. The whole analogy is invalid from an engineering perspective.

Hey Terrence…should the regenerator’s output come to
a clipping level…I think the regnerator would shut off by
going into auto-protect mode. (for the regenerator)…

That’s a good question for jamesh…

You may wish to ping jamesh with your question…
Best wishes…

Terrence get a load of this thread…

It should give light on the subject.

Scroll through the pictures and see the loads on the
P12 whith amp first current inrush and then at listening
levels…

The op has 2 Emotiva XSP1 amps running Class A 60w then AB
Plus a Plinnius on his P12…P12 taking it all in stride…no problemo
The opposite of what Garth Powell would have us to think

Good point. In this case, I really don’t need THAT conditioner. :slight_smile:

Hey jamesh thanks…but please clarify the “it would part”

The regen would put itself in protection.

Thanks, I recall that I did read some of it before. It has nice info (and pic too).
With all my gears plugged in, my P12 only uses up less than 160W.
Like others, get a regen is one way street, never look back. :slight_smile:

Thanks…I thought that is what you meant…but just
asked to be sure…

Way to go “whiz kid”

Terrence your P12 is beautiful piece of gear…
I went from P5 to P12…then a P15…

P15 to accommodate a Parasound JC5 Class A/AB
400 watt/ channel monster amp…

My musical enjoyment just keeps getting better…
your will also…

Guess what, I was watching this YouTube Sunday

Saw APC conditioner like mine there. My thought why this guy use APC conditioner in his super high end system…. He can definitely afford a better one.
Then around 34:54, P10 shows up. This definitely assures me my investment on P12 should be a good one. :slight_smile:

The APC seems to be powering his Tivo device, which makes sense. My concern is it’s a pretty bargain basement APC.

The structure of the walls (7:15) proves that he was on a mission from the start. I suspect he started building during the Cold War, just in case.

For the $1.75m that it cost him, using my normal metric of the equivalent number of opera/ballet/concert tickets that the expenditure represents, my wife and I could go to anything we wanted every day for the rest of our lives, so an easy decision. I’m sure it’s a nice system, but not for me. He does come across as very sane for someone who is obviously completely mad, in a good way.

Don’t get upset but I couldn’t very far thru it. My impression was that all of this was not much for the sound.

Compulsive behavior.
Sad that he will not get to hear most of that massive collection of vinyl.
