Sending a 110 lb amp to the manufacturer for cleaning/calibration. Good idea? How to ship?

Hi All,

So I reached out to Simaudio as my amp (Simaudio Moon Titan HT200 5 channel) is getting a bit long in the tooth. It performs truly flawlessly and is just beautiful and barely even gets warm after running all day long. I was just more curious than anything about lifespan, etc. Simaudio replied right away. They said all the units they'd manufactured since 2001 are still "active". However they did recommend sending it to them (if I could be without it for a few weeks) for "cleaning and calibration".  

Couple of things, I can't even go 1 day without this unit. But beyond that just the thought of packing this thing up and shipping literally makes me cringe. I'd certainly pay extra if there was some way to avoid UPS/FedEx or any other means like that. Any recommendations and have any of you ever done something like this?

Would appreciate any advice. Thanks all in advance...
