From reading the title, my guess is that English is a second language for the op. (I could be wrong, and I don't mean to offend if I am) My take is that he meant his question to read: Is the Ayon Triton one of the best tube amps on the market? Secondarily, I believe he was asking for opinions on the Triton versus the Cayin he owns. In this context his post would be reasonable.
