Same exact story for me with intermittent popping and audio cutouts on my CAT12C amps. I sent all three of my amps in for repairs the first time in May of 2016. They were returned to me 6 weeks later. One of the amps was fixed but unfortunately the other two still had the exact same problem. I lived with the popping for several more months, but decided I couldn't take it anymore. It was getting embarrassing every time a friend came over to hear a demo of my "high end" system to then be so distracted by popping and audio cutouts. I sent the two still-popping amps back in mid-January and Mark/SpeakerPower still has them to this day, so I guess we are at 4 months and counting now without being able to use my home theater (6 if you count the first time they were sent in). Mark contacted me about a month ago to say the amps would be ready in a week, but multiple weeks have passed with no amps and no responses to my further emails.
When I had trouble with one of my Submersive's amps buzzing in the past, Mark sent a new unit right away and I just returned the defective one. I'm not sure why this policy does not apply to the CAT amps, but should definitely be instituted in the future if he has any hope of retaining customers.
Hi Nicholas. You already have an e-mail I just sent with more info. Your amplifiers are headed back today from SpeakerPower, as are the amps for 2-3 others. There was a miscommunication between us on authorizing the repairs to get shipped out which is now fixed/clarified. As with the warranty on most any company, we reserve the right to repair, or replace the items with refurbished or new units. Ultimately it's a cost and inventory limitation. We do much higher volume of SubMersives, and the Catalyst amplifiers are even more expensive than the SubMersive amplifiers. If we don't have amps on the shelf or on order yet, it's a 3-5 week lead time before we could possibly ship a new replacement. In some cases I will have other units on hand from testing, repairs, etc, and if I am confident there are no issues with them, we might send those as replacements. Apart from this hard to observe/diagnose issue, repairs on the SpeakerPower amplifiers have been very reliable over the past 12 years we have been working with them. The popping referred to has been observed in 10-20 units over the past 10 years and a few hundred units. It has proven to be a tricky matter to diagnose as our amp supplier has only been able to reproduce/witness the issue in 2 units at their facility within the limits of working hours. I have been testing units here, and we believe we have the most likely sources of the issue narrowed down. I will soon have a similarly repaired unit running in my home and another which has a different repair I asked them to try. I'll be observing it over a long period to verify.
