DBC - Thanks!

I do have a nice Fluke, and I tried to measure potential (both DC and AC) between the two pieces...but I totally forgot I needed to disconnect the ICs before doing that. I got no meaningful readings.

I'll do this again tonight and report back. Thanks for your suggestions!

Edit to add: Also, I did notice one odd thing - while I was behind the stereo rack, swapping ICs; I had the interconnects in my right hand, plugged into only the ZMA, and I bumped into one of the power transformers bell with my left hand, and heard a loud buzz through the speakers. I figured, I must have just given some of the noise a path through my hand to the ICs - no big deal - touch the Power Transformer nothing. Huh, Touch both Output transformers Nothing, Touch the other Power Transfomer BZZZZZZZZZ.

So for some reason, only one of the PTs was causing a buzz when I touched it. I have no idea if that has anything to do with anything, but thought I'd mention it.

LR, could you cover the Tranny's with something, or at least the one in question, that seems to be making the airborne connection...this would stop/block the noise transfer/connection?

How did things go with Zen-zilla at Palomino's & your Oppo/buzz?

I'll let Raven comment on or buzz investigations but we had a good session overall.  He basically brought his whole rig and we tried various combinations with mine.

We started by introducing the P10 (monster!) to my rig.  The effects were immediate and profound. Most noticeable was the improvement to the bass.  I have done a lot of work over the past couple weeks introducing bass traps in all four corners and the bass has really firmed up.   This took it up another significant notch.  Nothing subtle about it.

Overall soundstage was also sigificantly improved as was the definition around all the instruments.  Raven explained it well in an example where he pointed out you could hear and feel the bow resonating on the strings on the violin.

We also did some tests with my triplite isolation transformer.  I have heard both positive and negative comments about this unit and wanted to see how the waveform looked on the P10, so we ran it between the wall socket and the P10.  It amplifies the voltage about 3 volts and had a similar THD, perhaps a bit higher than straight out of the wall.  The waveform looked a little uglier though, more ragged on the back end of the sine wave versus the front end of the sine wave distortion straight out of the wall.

Still after Raven left, I did some A/B with the triplite and I still prefer it in my system.  However, I am now scheming to figure out how to at least get a P3.   I don't know about regeneration vs flittering, but I certainly heard the effects of regeneration.  It is indeed a "wow" difference.

I'm glad you heard a "wow" difference. I just have the lowly Power Plant Premier (though it suits my needs entirely) and I won't do without it. For me (maybe it was my 1932 house wiring and city power of the time) the Tripplites added more noise (PPP verified this) than they did good and I really relaxed once I replaced them with the PPP.

I just have the PS Audio Dectet in my second system, it does a good job, introduces less noise and hash than the Tripplites, but doesn't regenerate. One day I'll probably upgrade that Dectet to a regenerator if the money "holds."

I posted this in the Mystery Amp thread - the difference on Palomino's Rachel with the P10 was like 25% improvement, HUGE. With the ZMA, I'd say it's only 5% improvement - those big ass caps really make a difference!

When I got home, I put my little Zen amp on the P10, and it was like a bought a new amp...which is funny, because I haven't plugged in the Zen amp since the ZMA showed up. LOL

Tell me more about the PPP. Maybe there is a thread already.  It's more within my means right now.

Here's the product page (It has not been produced for s few years):

For what it's worth here is what Stereophile says about the PPP:

Guys, I want to add my two cents here, as I have owned a couple PS Audio regenerators and think highly of them overall. It seems to have come up more than a few times that the PPP has some issues now and then. Mine certainly did and I sold it. It would click now and then at night for no apparent reason. I sent it back to PSA and they 'fixed' it. It continued with the problem and I figured that it was just where I lived or something. After selling it I read on the PSA forum that there quite a few people having the same problem. Not to say that all odf them had this issue, but I do see a lot of them for sale over the years. It's too bad because for the most part mine worked great. That is just my experience. Now, I still believe in the company, and bought a used P300. It is really great and has the muti-wave II+ installed. I wouldn't go without it. I installed a fan inside it and even made a stand for it. Again the idea makes a lot of sense and is readily audible.

I've heard of this problem too. Must say I've never had one lick or one click of a problem with mine.

 In that case, you are golden my friend. That's all I wanted too, but it became a circus that I never intended to buy a ticket to.

As far as the P3 (750 va) vs P5 (1250 va) vs P10 (1500 va) ... how do you know which product you need?  Do you add up all your audio products somehow to determine what you need exactly?

I realize that buying a P10 would have someone completely covered since it's their highest level product, but what about the other units, etc. in comparison to what one's needs are?

I am running everything off a 250v triplite now.  I don't need much.

You would be absolutely fine with the PPP, plenty of headroom.

I run my Torri Mk III, my Rega with upgraded power supply, an SACD player, a Blu-ray player, my PWD Mk II and PWT, my DVR, two CSP2+ and a ZP3 on my PPP. With no strain, no pinch on dynamics, etc. And without a glitch from day one.

I have only the Rachael, a iPod digital transport and occasionally a turntable.   My current DAC runs off a battery.  The Mac mini is currently on a different circuit.

I was wondering if a P300 would do for a short term solution??

You could, but imo the PPP sounds about three times better than the P300. (I have one of those, used it for years til it crapped out, never have tried to repair it, I think it's just the power switch went out.)

For the price of a used PPP I'd say just hold off til one of those arrives.
