I have brought several Integrated Amps from them in the past 7 years and they have all been very reliable. As for questions and support they have always been responsive. I'm sure a lot of the parts that are used are source from China...but what isn't these days. Chinese sourced components can be just as reliable as components produced here in the USA, Japan or South Korea as long as you know what you are buying. It is my understanding that they assemble the bulk of there amplifiers here in the USA. In the seven years that I have used their products...reliability has not been an issue. They maybe sourcing all or most of their tubes from other Chinese companies but that is OK with me. It saves me the hassle of having to deal with an oversea company directly. I have also always been offered the opportunity for in home trials with no obligation to buy with full refunds or credits for other products upon returning an item that was not to my liking.
