khartago v. rotel 1070 power amp

I have a Rotel RB-1070 powering some B&W 804N speakers. It does a nice job of opening these high-current speakers up. I am looking at possibly upgrading to the RB-1080 but am waiting unitl the fuse/capacitor issues are worked out. I am not familiar with the Khartago amps.

"I am looking at possibly upgrading to the RB-1080 but am waiting unitl the fuse/capacitor issues are worked out."

What is this about? I'm curious because I have the RB1080 sitting in my closet. I need to sell, but I like it to much to.
