The way it is described, I have to agree about taking the Pure Power to a trusted local repair shop to get it scoped out.I will just say again that repairing the Pure Power seems to fix the problems, for those who have been able to get their unit bac...

[quote user="Romy the Cat"]Let leave aside the probability
that you specific PP is defective. If it is then all bets are off.

[quote user="N-set"]
They have figured out a way to
eliminate this but it requires making a new PCB to replace one in the
PP2000. So they say they are going to make these and hopefully the
replacement PCB will be given to me in a month." [/quo...

In regard to the noise issue I had with my Pure Power unit in the past, I never noticed it with my tuner or other components, but I mostly listen to the phonograph. In particular the Decca cartridges are incredible as antennas and seem to pick up all...

Jarek, When you say "not 50 Hz hum" it reminds me very much of my troubles I had with my Pure Power 1500 -- (before it "blew up" and needed to be repaired ... ultimately replaced with a new PP 2000 plus by Damien) -- but in any regard, the hum was ca...

I can only suggest to keep calling them. The product itself, as we all know is outstanding and makes everything else in the category look like garbage, but the service has always stayed at the level of a one-man operation. If they can get their servi...

Agreed. I also had this issue with my Decca cartridge using the Pure Power and physical separation works well....

Every resistor, capacitor, tube, etc. are just physical devices that are optimized to come a bit closer to an ideal device -- a wirewound resistor may represent an ideal resistor, but it has inductance, capacitance, and other electrical and physical ...

[quote user="Romy the Cat"]PP does inject very positive qualities to sound and it is in part might
be because it addresses some of intricate electric problems but we, or at least
I, do not know it with certainly. The claims that PP manufacturers ma...

The famed audio designer was working on new audio designs until the end, which continued to be published in MJ, the Japanese audio journal. I'm sad to hear of his passing. I feel fortunate to have been able to meet him and spend time listening to som...

[quote user="Romy the Cat"]This is why I am a bit skeptical
and with big worry hear news that PP did some improvement. [/quote]Since (at least comparing PP2000 and PP3000+) PurePower is still effective, the one thing we can say is that PurePower has...

It is always entertaining to see a story about PurePower. I say simply that Richard should make good on the refund as quickly as possible.I am always surprised to hear about customers who are surprised about this sort of thing happening with audiophi...

Romy,I agree with the very nice summary you have made of the situation. You remember that I struggled for a couple years to get PurePower to return my PP2000 which had gone for repairs, but ultimately they replaced it with a PP3000+. I just have to ...

While I and a few others have had some delays with PurePower, they came through in the end with an outstanding product. I have grave suspicions about a post complaining about PurePower and simultaneously promoting a link to the "ProPower" company, wh...

I think this is all fine, but since you are building it all, why not make it so that you have the flexibility to experiment with different configurations to see what works best in your system? I think it's fine to have a theory about clustere...

The ground simultaneously serves as the source of all electrons entering the system and a common voltage level that establishes a baseline for the system. Thus, the ground should be simultaneously as large a homogenous metal source as possible while ...

Ha! Criminals is going a bit too far, unless you want to call all the audiophile companies criminals. I am not saying that is not the case, but the behavior of PurePower is not different from many other audiophile companies or many other similar busi...
