PS 1000 doesn't seem to isolate as well as expecte


Hi Guys,

I'm a neophyte. Been listening to music forever. Became an audiophile a few years back. Despite my board name, I'm a contemporary jazz listener. I listen to stuff I-tunes doesn't sell. Watercolors is a good idea of what I like. And of course... Keep on Rockin.

I have a couple PS Audio, PS 1000s and a Premier.

I'm listening to Martin Logan SL3s with a PS1000.

I had a wake up call. I turned off a very small light and there was a noticable "Pop" from the speakers. This is unsettling. What do you make of it? It repeated itself.

I just set up a new listening room in a new house. What bliss. It's been 18 months this time that I've been an audio exile.

Right now I'm patching together some stuff.

Q-Sonix 100 (running analogue out) as a source
EAR 868 as a pre-amp
Red Dragon Leviathans amps
Martin Logan SL3 speakers
No special ICs or PCs in the system yet. Onix speaker cables.
Exemplar Extant DAC out for repair.

I'm saving the good stuff...
Epiphany Audio 21-20
Bob Carver/Tim DeParavacini very low production tube amps
Bybees
Virtual Dynamics (I bought Rick Shultz's personal cables)

Plus, I'm going to vinyl. Building a TT based on an 80s Victor 801.

But.. That Pop !!

Any thoughts?

I'm learning.

And loving the heck out of it. I never knew it could be so good.

My thanks in advance,, and,,

Keep on rockin ! :)

This has me stumped since all your electronics are isolated with the use of the Power Plant. I would have thought that any spike and/or interference introduced into the power line by a contaminating source on the same circuit would have been filtered out.
Exactly my thoughts.

I spent some fruitless hours trying to set up a second system this afternoon.

But I did some simple tests. I wouls have no music playing. I turned the light on. I could hear light clicks from the right speaker synchronized w the flickering of the florescent light coming on. Then the loud pop turning off. Same thing three times in a row.

I don't believe it was effecting the left channel. It is further away.

I'm thinking airborne RFI. The powered speaker has something to do with the magnitude of the pop IMO.
Florescent light in or around audio equipment is a big NO-NO! Several threads regarding this have been discussed in the past. Do a search and read the replies/ remedies.

Can you replace with LED or battery type halogen?
Transformers/ballast in florescent lights and light dimmers are well known for introducing noise into the ac circuit. I would have thought that this noise/interference would have been filtered out by the PPP. Can you put your PPP on a different curcuit?
Are your ML stats isolated? Try plugging them each into their own isolated receptacles. Make sure that the amp that they are connected to is also isolated on its own.

If this fails, I would contact Alex at PS Audio to get some advice.

If it is at all practical, I would highly recommend running a dedicated line(s) to your system. I realize that this may well entail tearing out some drywall, but the results are well worth the effort.

Let us know how you come out…

Note: owned a pair of the SL 3’s years ago. I remember that the midrange and treble regions were outstanding, with a huge soundstage.
