Ugh, I hope that this community doesn't become like head-fi where people believe they can hear differences in DACs, yet refuse to test. Statements like "I trust my ears" means you are very likely to waste money, a lot of money in this hobby. Not trying to be mean but the X16 is not going to sound more musical than the D90. What the heck does that even mean? If you can't absolutely describe what the differences are and also relate those to technical explanations for it, there is a great chance your mind is playing tricks on you. Head-fi is a the best place for the I don't need evidence hobbyist, and no problem there, if that is your thing great, enjoy things your way.
I can barely stand head-fi anymore. The members there are very, very nice, and they love the hobby and sharing their passion, but some of the most ridiculous things I have ever read come from there. I just left a thread where some member was talking about how he dropped mega bucks on cables and treatments that he and his wife both thought made great differences, all of his friends agreed as well, and to top it off he noted how the salesman at the audio shop where he bought everything complimented his ability to detect these magic differences. The poster believed that these ridiculous endorsements constituted evidence of audible improvements. A fool and their money is soon parted as they say. I know that is harsh, and I don't imagine the person is a fool, just highly suggestible.
Anyway, I do greatly prefer far less subjective content, although I do realize it is hard to avoid some and I even enjoy some myself. But please, no claims of more musical sounding without a real explanation for what that means and what design aspects of the device could possibly produce the results. Then ideally, some evidence to support the claim. Rant over.
