P20 AC Power - value in the P20 over the P15? 20A power cord?

I also recently added the Denali 6000T and SR Alphas from Denali to Outlet and for Amps, and SR Deltas for Sources. So far, I like them a lot. Heard great reviews for SR digital cables as well.
Best,
Thanh

Why did you choose /T instead of /S?

The T has cradles in the back which hold the SR power cables firmly in place and there is no risk of drooping. I like the look of the T and it’s also easier to position near your rack.

Do the HC outlets sound different to Z1/Z2 outlets?

I plugged my amp (Bryston 9B) and preamp to the HC outlets (20A), and my DS Sr. And Oppo player to the other outlets (15A). I have not yet tried to switch things around, but I suspect that there would be no difference in sound coming from HC versus Z1/Z2 inlets as long as the components do not require a full 20A capacity (such as high-powered amps). Hence, for my monoblocks, I connected them directly to the wall outlets (20A dedicated line) with SR Alpha NR. Also, I installed a whole-house surge protector at the electrical panel, and it is working well.

No P20?
And please let us know your thoughts on the Denali.

So I have the alpha HC 20 amp to the p20 and alpha NR to my amp.

I just switched out my outlet from my soloist to a Furutech NCF duplex, I am sort of surprised, it’s almost like a power cord change, in a good way. Since folks in this thread seem to enjoy this type of thing I thought you should know and maybe give it a shot. Or maybe you guys have and I am late to this game!

Oh and I just ordered the sigma for the amp and will move the alpha to the pre and another alpha for the dac. Will let you know.

No P20. I’ve moved on.

On conductor-size requirements for AC-current maximums…
Many of us don’t realize that there are cable-length and permitted-Voltage-drop specs inherent to the AWG-conductor-size-requirement tables… Who knows the mazimum length permitted with 20 amps @ 120VAC drawn thru a 10g. cable? How about Voltage drop? I understand–that is, I don’t KNOW–that some of these tables permit a TEN-percent Voltage drop over the permitted length; who of us would willingly buy a AC cable that suffers a 10% Voltage drop?

I’m slowly moving up in conductor size as I improve my power quality (that means power-conditioner quality) and replace p-cords, etc… My three dedicated branch circuits into the musicroom are 11g. (two times 14g. per pole), I’m using a current-generation Neotec (NEP-3001 Mk.III) 10g. cable with a 20-amp IEC feeding my 20-amp BPT balanced-power p-con, current-gen. Neotec 11g. cables feeding my DP and preamp, and 18- and 22-foot 8g. (2 times 11) cables feeding my two 60Watts-into-8 Class-A, tubed poweramps. Bigger is NOT always better, but all other things being equal, I believe that bigger AC cables are better than smaller ones (WITHIN REASON, of course). :slightly_smiling_face:

I’m currently beta-testing a prototype of a very-high-quality powercable that starts out with six 11g. conductors and is usually assembled as three 8g. conductors (as mine is)… It sounds VERY good and better than the long pieces of current-gen. Neotec 11g. that preceded it, but the supplier asked not to be named until they master the complexities of affordably terminating this stuff.

Meanwhile, I’ve ordered a P20 that should ship by the end of next week; wish me luck. :slightly_smiling_face:

I didn’t read the whole thing but the National Electrical Code allows 5% voltage drop total (feeders and branch conductors) and 3% on a local branch circuit. There are sone easy to apply formula available for figuring out voltage drop based upon load and conductor size.

I should think, we all wish you luck with that. Both getting it out the door on schedule, and everything after that.

Geez, Brodric. Maybe more fiber in your diet.

Oh, of course, my bad. It’s a 120V P20, so no luck required.

How’s the Denali treating you? Now that my P20/P15 escapade is coming to a close I’m deciding between the Denali and the Furman IT-Reference 20i. It sounds like the Furman would be much closer to the P20 in terms of output impedance/power reserve (sans regeneration) where as the Shunyata is strictly a filter.

I’ve read this part of this thread a few times and still don’t know what this means.

RonP?

Just a cord made with parts from Home Depot. What goes in does not matter. that is the entire point of this device. It is what goes out that matters. Spend on power cords to connect from P20 to your components. In the instance of this device a power cord going in should have absolutely no influence on the sound. Wasting peoples money. correct me if I am wrong.

I am not interested in correcting you. You do what you feel is best. Me, I have a high quality power cable providing power to my P20. I am fine with this as you are fine with yours perhaps. Go and sin no more. :wink:

I just found my meter. My meter reads noise in ā€œmvā€, Millivolts. My wall is 270mv. The P20’s read 34mv. My new Torus RM15-AVR reads 1mv. The lowest the meter goes. I take it that means the Torus is more effective at removing noise. I cannot comment on the sound as they are in two completely different systems. Respectively both systems sound very good to me and better with power conditioning/regeneration. I was surprised however the P20 did not go to 1mv as well. Perhaps that is inaudible to humans anyways. I don’t know. What was important to me is the Torus being completely passive does not buzz. since this is in our bedroom. Also amps are fine on the Torus. Amps do not sound good on the P20’s here. I have no idea which one is in fact ā€œbetterā€, if at all. However it was a plus to me in the bedroom because there were not enough outlets nearby. Plus the bedroom is not a dedicated line. The P20’s are on separate 20A lines all the way to the transformer. Our farm has 3 of our own transformers feeding no other property. Can anyone explain what these readings mean, if anything?

Paul has said many times before, the most important power cord is the one that connects the power plant to the wall. So your best power cable is used for that purpose.

Mileage can vary on that point. Some find amps to the wall better. Some find amps to the power plant better. So many different amp designs out there that react differently in different situations. For me, amps to the wall.
