This is an amazing package. It is a tube amp in compact size. Prima Luna is designed in Europe and manufactured in China. I have been using it for about three years in an upgraded system, including a Proceed PRE and a pair of Thiel CS2.4 speakers. The combination is truly outstanding. This amp is in virtually the same condition as when I bought it. I estimate the tubes have 3-400 hours of use. It has only about 36W per side, but you should hear how it drives those 70 lb. Thiels. Best amp I have ever owned.
