I have Thiel 1.5's and I love the detail I get from them. I am using a VPI mk4 turntable, Pioneer CD 54 stable platter CD player, Audible Illusions M3A Preamp and I just got a Audio Research 100.2 Amp. This amp with the M3A preamp really makes the Thiels sing. I was disappointed with the sound of CD's before I got this amp, but now they sound great!
