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 ! :)
