popping from speakers?

Most manufactures of CDP’s recommend leaving the equipment on.

ya. sorry realized after i posted that you may need more info.

i did purchase a new amp - tube. however, this was in hopes of fixing a similar problem. the old amp, a transistor, was sparking. i'd figured it somehow got fried so i got a new one. this time a tube amp.

still didn't work so i tried a ps audio unit to clean the power.

today, i tried to make sure all cables were ok. i disconnected everything and reconnected.

i have tried putting in new tubes. no go.

i'm not sure i understand all the "floating" the ground stuff. sorry haven't ever played with electrical.

i can try the component first thing but i think i used to do that with the transistor amp and today i was just trying to narrow down if there were issues with the amp and the speaker since it's the new thing.

any help is appreciated. have put enough time and $$ into this problem and am a bit frustrated. in fact, this is obviously over a bit of time.

thanks for help.

Switch your speaker cables and see if the popping changed to the other speaker. Do the same with your interconnects, one set at a time. You may have a bad termination on one end of your cables.

I had the same problem when I added a dac into my system. So, the culprit had to be the dac. I sent it in for a thorough checkup and the problem was narrowed down to a loose solder joint. After that was fixed, the popping went away completely. So, maybe you can try to check your components for any loose joints (it's no easy task). Hope this helps.

Cheers.
