Is there an irritating hum coming from your system?
If so, try touching it. If the noise increases, it’s missing a earth/ground and you need help.
Step forward, the Groundhog+.
Groundhog+ comes with an extra cable so you can connect it to our very own AC iPurifier.
Hit noise even harder.
Attach the banana connector to the AC iPurifier and the RCA connector to your amplifier.
Not only have you added back the shielding provided by the Groundhog+ but you’ve stopped outside interference as well.
