I actually was the importer for one of the Chinese brands mentioned above for several years. Obviously, there are a lot of stories to be told about that.
In general, I would say that if you are going to buy one Chinese high-end audio product, it would likely best be a low cost tube amplifier. In my opinion, as soon as you hit midlevel, you're far better off buying something made elsewhere. The poor resale of Chinese components is reflective, among other things, of the ZERO pride of ownership that comes with the territory.
As I currently own both products, I'll echo the Dynaco and Quicksilver recommendations. You can also do very well (IOW - a lot better than the Chinese kit) by looking into used products from the likes of ARC, Cary, Jadis, Manley, VAC, and VTL.
