Is it all in my head?

Okay, sad to admit it but I just did an a/b comparison, granted it was only on one dubbed cd, between my musical fidelity a3.2 cd players dac and my new parasound z dac and could hear absolutely no difference. When I got my dac a few days ago I thought it was the best thing since sliced bread, but spank me and call me sally, I can't for the life of me distinguish between the two. I hooked it up such that I could go between the two on the fly with a press of a button. Hmmmm... I could hear a difference between my denon dvd 2900 and the musical fidelity a3.2 but no dice between the a3.2 and z dac. I can also hear slight, slight differences between i.c.'s and speaker cables so I dunno. I think I may be spitting the kool-aid out if it doesn't give me a buzz anymore, or else I'm gonna buy some of those ufo thingies to put on my windows (sorry G).

Doh...
