jusam - a note about the CS1s. The CS1.2 was designed as Jim got his feet wet with Finite Element Analysis. Its drivers included our first aluminum tweeter and our first use of copper shunting rings and sculpted gap pieces in the woofers. As such its performance stood well above its CS1 predecessor. However, the CS1.5 followed the intervening and envelope-stretching CS5, 2.2, and 3.6. Each product design in Thiel’s history represents new lessons learned, technologies developed and resulting higher performance. It’s no accident that the CS1.5 hung out on Stereophile’s Class A (limited bass) list for so many years. I suggest going for the 1.5 if you can.
