Ashgar,
Congratulations! I've heard and read many positive comments about these amps, but I have not yet heard one myself.
I have one correction concerning your statement, "...of course it is Chinese made..."
You are correct in that most or all of the parts are Chinese made. However, these amps are assembled by a very knowledgeable and experienced Taiwanese gentleman. [I have not met him, but I know several Taiwanese audiophiles who know him.] One other interesting point is that he made some improvements/upgrades to the amp you have <at a higher price>, but I believe the improved version is available in Taiwan only.
