When my system is idle, I am occasionally getting some interference-type and crackling sounds through the speakers. The interference sound s followed by the crackle, then silence again. They are independent of the volume control, and muting does not help. They don’t seem to be loose connections.
It’s SN1-HiCap setup. Both are getting on in age, and the HiCap is older by quite few years, and I’m suspecting the thing needs a service.
Any thoughts?
Winky - It would be worth running the SN1 without the Hicap for a while to see if this device is causing the issue. Otherwise a complete disconnection and reconnection of the system cabling would be worthwhile too. Always worth a check around the house for any electrical devices switching on and off at times when you get the crackles.
It could be the capacitors in the amp starting to fail, although I don’t know how susceptible the SN1 is to the ageing capacitor issues.
It could also be a thermostat somewhere in your house or apartment, such as on a water heater or fridge, causing interference.
I had such a thing recently, rerouted cables issue gone. I think the snaic was too close to a power lead.
