I recently purchased a pair of Swan T-200c speakers. They sound amazing, but after roughly an hour of use they emit a clicking noise that increasing in volume. This persists after I unplug the audio connection from my laptop, so at this point I've assumed the problem is with the speakers themselves.

The company that sold them to me offered to replace but also suggested a few things to try first. I have so far:

• Purchased a much nicer power strip, one with power filtration (my old strips were 10+ years old and from before my undergrad days, read: not great).
• Moved my setup away from my normal desktop area where I was nearby the tv and washer and dryer into a room where it's the only set of electronics other than the lamp above me.
• Monkeyed with the positioning.
• Made sure all the cords are fully in.
• Fiddled with the switches on the back of the master speaker.

The only thing I havent tried was putting a ferrite core around my power leads. The power cords themselves seem reasonably shielded so I'm not sure how much this would help.

I did just get a copy of the owners manual (new product, distributor just received it from manufacturer), but I havent taken a deep dive into it.

I am at the limit of my knowledge. Is there anything else someone can suggest or do you think it's time I spent the money to send it back. I'd hate to give up an otherwise excellent set of speakers if I can adjust something at home.
