UPDATE: I haven't received a response in over 2 weeks from either their customer service department or technical service departments. Th...
I was wondering if any of you might know what is wrong with my pretty much new Emotiva XPA 2 G2 amplifier (http://shop.emotiva.com/products/xpa-2-gen-2).
First off, I'm located in Canada, so they handle warranties differently than being in the States.
I received it back in September and since day 1, its been making this annoying clanking/clunking noise every time there is some kind of shift in output. It sounded like some kind of thermal issue where the heat sinks made a sound every time they had reseat after expanding and contracting to heat.
After contacting Emotiva support, they told me to take apart and put most of the screws back together on the chassis after a month of back and forth. I did that, and the first sign of doubt in product quality came with the fact that half the screws weren't even tightened underneath the chassis. I could twist most of them off with nothing more than a twist of the pinky. The ones inside seemed a little better, so I tightened the ones under the chassis and marginally loosened the ones inside. Voila, part of the issue was kinda fixed (thermal expansion and contraction clanks still occur maybe twice a day instead now instead of every 15 minutes).
It was at this point I realized that the problem wasn't a single issue, but actually two. Now that the contraction/expansion issue was (largely) out of the picture, I realized there was another more distinct clunk coming from inside the chassis whenever the output increased, decreased, or went silent. Under normal usage, it occurs maybe every 20 minutes to 2 hours depending on how many prolonged jumps from silent/loud to loud/silent there were. It sounds like those clunks you hear from a lot of amps during start up (the relay clunks similar to the sound a receiver makes when it activates its amplifier shortly after start up). Not only that, but the issue started getting worse and it actually began making these clunks even after the power was off every few hours. Maybe 4-5 hours after the unit has been turned off, there clunks would stop until you turned on the amp again.
My inspection process:
-Checked other outlets and power strips
-Checked interior for obvious parts damage
-Checked individual sources and cables
-Checked sound output quality
After a while, one of the Service Techs sent out a replacement revision 1 power supply board for the revision 2 I had in my unit for free. I swapped it and the issue was the exact same.
Everything seems okay, but this annoying clunk keeps happening, so there is obviously something wrong. After 2 months of back and forth for an issue that came new in box an Emotiva Service Manager has told me to get in contact with a service depot in the Netherlands so I can send it to Europe for service (keep in mind, I'm in west coast Canada). I'm not too keen on sending my American branded, Chinese assembled, Canada landed amplifier to Europe. Shipping alone would cost a stupid amount. There is no way the only depot they have is in the Netherlands, is there?
Is there anyone who has had a similar issue or might have a guess as to what the problem might be? Any help would be appreciated since the alternatives include liquidating it or spending a stupid amount to ship it to Europe. No matter how basic or stupid the advice might sound, I want to know because I'd rather have a stupid fix than a broken amp!
This was actually my 3rd amplifier from Emotiva, and I was totally happy with the previous two, but I think this will be the last thing I would get from them. Their QC is seemingly lacking, especially when they claim to check every internationally outgoing device individually. I really question their QC claims as the chassis was literally held together with screws that were falling out and the clunking/clinking was the first thing I heard before even putting a source into it.
I can't help but feel robbed getting sent a lemon product. But I knew the risks involved with landing this device in Canada, so SOL for me I guess? I urge international buyers from Emotiva to be fully aware that they are not getting properly tested products, and if you get a dud, there is a chance you will not be able to resolve the issue and be left with a lemon product. Mine is almost unusable because of how annoying the clinking and clanking was fresh out of the box. That being said, the price is hard to match if you want something new. Its all about weighing pros and cons I suppose. Ignoring the clanking, this amp is a beast and a half for a lot less than Canadian priced equivalents NIB. One of the few times I wish I lived in America instead.
