REL Strata III - faint crackle/pop sounds

Well, that's what I'm worried about. If I go through Sumiko or one of their dealers, it might end up costing more than I paid for the sub in the first place.

Anyone know of places here in Northern California where I might be able to take the sub to be diagnosed and repaired? I'm sure there have to be skilled, reputable places out there...

Thanks!

My unit has always made a pop/hum sound when first powering on, but the issue I'm having is after the unit has been switched on. There's a faint crackle sound, kind of like what an old, dusty record sounds like.

Frankly, I haven't tried to play much through it since I've started hearing the crackling sound - I don't want to aggravate any issue the unit might already be having. And plus, since I've heard the crackling, I know that's the only thing I would hear anyway.

My Strata switch light burned out a long time ago. =)

To follow up on this thread... I finally ended up calling Sumiko Audio because I happen to live nearby in Northern California. I worked with Kendra in customer service and she was very helpful in arranging for diagnosis and eventual refurbished replacement of the amplifier board ($100).
