Mine used to click every time I used them (quite loud sometimes) and even up to 8 hours after turning them off, but a couple of days ago I disconnected the amps and turned them on their side and loosened the five screws for each of the heat sinks on the bottom of the amp (they are about in line with the amps feet) and using a screw driver (just between my thumb and first finger) I did them up barely even finger tight and they haven't made a noise since. I would be concerned that there not making good contact now , at least with the clicking you knew the heatsink was doing its job and getting warm |

I don't know alot about amps etc , but I do know alot about overclocking and I don't see the heat sink for a amp being to much different than a heat sink for a CPU , the heat sink is on top of something keeping it cool and when its clicks -- expands and contracts to me it would tell me its absorbing heat , now the clicking is gone my guess because its not tight enough . And if they used any type of thermal past its not good to loosen a heat sink once its tight youll end up with bare spots |

have been thinking about converting my cooling over to liquid but i just cant justify it as my gaming demands really dont require anything more than about 1/64th of the system i have lol...
off topic i know....im bad today with that.....

Edit: one just made a small click just now... 11 hours after they were last used, but still they are much better than before. |

I just bought two XPA-1's and am certain that if I get some clicking I'll be on the phone to Emotiva abuot a fix. However, I'm not worried about it...I believe they know about the issue and have solved the issue.

However, I'm not worried about it...I believe they know about the issue and have solved the issue. You would think that, but I just bought my XPA-1's about 3 months ago. If they know about the issue then it should be fixed. They shouldn't have to have the customer call and then say, "Oh yeah, we know about that....here is what you need to do." It should already be fixed!!! I am still getting the clicking and I will be calling them up next week. |

However, I'm not worried about it...I believe they know about the issue and have solved the issue. This issue has been around since they started making them. I had 2 about 3 years ago. One of mine clicked. And seems you guys are still getting the click. It drove me nuts. But I loved the amps. |

There is nothing to "fix". The clicking is nothing more than the expansion and contraction of the metal in the heat sinks of the amp. It only proves that the heat sink is doing its job.
Sometimes, the clicking can sound louder and most of the time that is because of the resonance from the surface the amp is sitting on. Move the amp or place something under the amp to decouple it from the shelf it is sitting upon. The more effectively the heat sink performs its job, the more likely you are to hear it click.

I have 3 XPA-1's driving my front 3 channels and I can hear clicking sounds during music and movies and even when they are off in standby mode. great sounding amps but to an audiophile like me hearing clicking sounds during 2 channel audio nirvana is a deal breaker. I'll be calling Emo to get it fixed or they will be sold. I agree with the guy that said for a reference level product this is really dissapointing quality. All 3 of the amps are less than a year old!

As I posted previously, neither of my XPA-1s have ever clicked but I'm glad to know there is something to try if I ever experience this. |

BS there is nothing to fix!!!! Do other amps in this price range click because of their heatsinks expanding?  I know for a fact that sunfire and odyssey amps don't click. THIS IS EMO'S REFERENCE LEVEL AMP AND IT HAS A KNOWN ISSUE THAT THEY HAVE YET TO FIX. That is completely unacceptable. Also, why the hell would I ever open up the amp and loosen the heatsinks. That is utter retarded. I am not going to go d***** around in the amp and possible void the warranty. This is a manufacturing issue. Anyone who can't see that is blind IMO and a complete EMO fanboi! |

^ One votes with one's wallet. I would have thought that a manufacturing issue would affect more than just some amps. FWIW, I had a $5k Proceed amp that clicked when the heatsinks were doing their job. They replaced it with another one and it too clicked. They told me "The clicking sound emanates from the expansion and contraction of the heatsinks and illustrates that the heatsinks are operating per design". I got used to waiting for 15 mins for the amps to warm up before doing any critical listening. Hey, it gave me excuse to use the FM tuner! Maybe this makes me a fanboi heatsinkboy!  |
