Left channel crackling noise again

[kvandhi]

Hi

I have Marantz PM5005 stereo amp purchased in 2016,couple of months back facing left channel crackling noise issue. Auth service center replaced PreAMP in the amp and returned. Again the same issue(crackling noise) in the left channel.

When i bring the amp to service center, its working fine and no issues. Would like to know, is there any issue with Speakers or Speaker cables causing crackling noise.

Any pointers will help me to proceed.

Setup:
Laptop - Nuforce Udac-Marantz PM5005-Scansonic S4 speakers
Cable - DAC bought from Hifimart along with above setup

Did you try a different power source? Is the crackling present even when the DAC is not connected to the amp?

Please interchange your speaker wires and check. I faced similar issue with my Amazon basics speaker cables long time back. I had to tighten the inter connects and it worked fine.

How long we can use same Speaker wires for connecting all sources till speakers. Should we change every few years ?

If you are leaving near sea facing/salty area , corrosion of component pins can be the culprit. Same thing happened to my NAD C352, I desoldered the preamp modules, scrubbed away its pins and resoldered it.

If there is balance control then open the cover spray wd40 on the potentiometers.

don't waste your money on gold plated wires. Just a good copper cables do the job. No need for 20 years at least. At least once in five years clean the speaker terminals with wd40.you just peak in side your amplifier and see what cable's they used for internal wiring you will be surprised its just ordinary multi strand copper cables. So zero oxygen etc are just for pricing.
