Anyone own or heard of PrimaLuna?

Hi. First of all, I am not an audiophile but simply love music and like it certain way but not overly crazy. I started out with solid state Mcintosh for couple years. I recently listen to few tube amps like audio research, t+a, cary audio and prima luna. I can afford all those big expensive brands but I thought primaluna sounded as good if not better and it cost fraction of other big names.  Just curious if anyone has experience with it? What you like the most? What you feel need improvement? Any issue with customer service? How's the company? Is quality really that better as they claim against other competitors? Thank you for your feedback.
