Good Evening,
I personally own and use a Shanling STP-80 Integrated tube amp. It's made in China. I have been very happy with it for almost two years without any problems. Yes there are some poorly made Chinese amps out there but there also poorly made American, British and European ones as well. I usually find that there are some very xenophobic attitudes in the HiFi world. People should not forget that most of the Reference and Synergy lines of Klipsch are manufactured in China. I have my amp hooked up to a pair of Heresy's and previously to my RF 35's. Sure it's not the best amp available but it allowed me to enter the world of tubes at a reasonable price. I can definitely tell you that now that I'm here I will not be going back to SS. Will my next amp be Chinese? Maybe. I will definitely upgrade to a higher quality one, if that happens to be made in China I'm fine with that.
Don't listen to other people's opinions when they have never had personal experience with a certain piece of equipment. Try it out and decide for yourself.
Good Luck
Coltrane
