It is fun to hear the differences in IC's but I would suggest you leave the Transparent IC in your system for awhile. Once you hear it over a period of time then change IC's and the differences will be greater IMHO. Hearing a difference and hearing over time what will be the most musical IC can be interesting.

By the way the PBJ is a stranded cable and not solid core. I owned PBJ's along with 4VS speaker cables and they had all the problems I do not like with stranded cables.

Glad you are enjoying cable discoveries. They can add to an already good system.
