oh, no need to say sorry, we are sharing the view after testing, it's the real test so better than only listen from others, i also planning play CAS not now, so i just try to rip CDs into computer, 至於綱上or 什志的文章我會看了之後自已親身試下, 其實test it so easy , just rip one cd, then will know the answer by your own., 我也會在有時間時試下不同版本CD rip 前/後分別
