Do you have tin ears?

About a decade ago I jumped into the audio craze and went at it full force. With my budget at the time I purchased the best of the best that I could find through Audiogon or purchased it new. I had problems with my tin ears. I'd have 8 or 9 pairs of IC's and they all sounded the same. I couldn't tell A from B. They all sounded as good to me. I spent a considerable amount of money to find that special cable and never found it.

So, this time around, as I put a modest system together with pieces from back when and and maybe a few new things, I am approaching ICs differently. This time I am going to purchase something solid and durable and stay there. I may consider something by Signal Cable or maybe Blue Jean Cables. Signal cable makes some durable stuff so that may be my ticket

How about you guys? Any others with ears of tin?
