Popping when kids are jumping

Gentlemen, I’m not sure where to post this but I’ve noticed recently when the kids are playing and jumping my PMC twenty.26s are popping. It’s subtle and I only noticed it because I was sitting next to said speakers.

I’m not sure where to begin figuring out what the problem is.

The chain is PMCs with blue jean cable on the plinths, spikes and feet. My amp is a plinius sb301 and not on a plinth. My DAC is an amr dp-777 and in a cabinet which I believe to be sturdy enough.

Any advice would be great appreciated, please.

Thank you

It’s a 6 year old condo and I wouldn’t be surprised if it was a wiring issue. How does one confirm that? I’m using Sonos, sorry for not mentioning it. I checked all connection and they were tight, I’m about to check again. The popping comes from both left and right and sounds like more the mid and tweeter.

Disconnect everything but your amplifier.

Dance around and see if you still get the popping. That reduces your issue to power or amp.

Pardon the delay, busy week.  I turned on only the amp and hesitatingly jumped, jeez it's awful.  Turned the amp off, dac on and gone.  We have hardwood floor...should I get a plinth for the amp?  Call an electrician or is this something...I dare do myself?  

Thanks again gentlemen!

It sounds as if from your description that some connection possibly speaker binding post inside is loose in your Plinius amp.

OK, so it’s likely the amp. Turn it off. Open the amp. Turn it on with speakers connected and no inputs. Use a thin wooden stick to gently prod at different parts inside the unit until you cause the popping. That should indicate where the fault lies.
