Hi Kaneson,
Well, in that case, make sure at least that you can trust your dealer after purchase (FYI, Cary CDP is actually "assembled" in HK, and maybe a good deal there). As to auditioning CD, I don't know your taste in music, but as a classic lover, I would bring my favorite (1) violin solo, (2) piano solo, and (3) symphony. Make sure that you listen well those CDs with your current setup before auditioning the new equipment. I use (1) for clarity + detail, (2) for overall frequency response (piano has very difficult lows), and (3) for how well it reproduces complex passage. The point is how you will like the sound of your favorite music reproduced by respective candidates. Good luck!!
