Any US manufacturer of a 845 SET amplifier

I listened to a Line Magnetic 845 SET amp and was very impressed. It was very well built. My concern is not about build quality, however I am concerned about service.  Anyone know of a US company producing such an amp?
Thanks all. I should mention that my budget does not exceed $5000.

@goldprintaudio  thanks for chiming in. I had you on my list as a dealer to call regarding my questions concerning LM amplifiers. I will do so.  

At the moment I am in a quandary as to going to an integrated vs. looking for a tube amplifier to rotate with a SS amplifier using my Aric Audio tube preamp. 

From my observations the Tone Import web site doesn't supply much info regarding LM. I had planned on calling them to find out more regarding the service facility they use.   
Feel free to send me a PM on here or email and we can chat about who does the service work/etc.
