Me making claim? What did I claim? All I ever said was he claimed something and I asked what do you guys think about his claim. I didn't try to take his claim as a gospel or reverse the engineer to make competitive product. I'm just curious in how it works. There might be some of off-topics debate about CD VS SACD but that has nothing to do with A+. If it's not possible to find out. That's OK. That's all.
