I have two pair of AC level 1 speaker cables that have been stored for more years than I can remember. Went from ultra expensive MIT (great, did not like the water hose size nor the multiple network boxes aspect) to Audience AU24s nearly as good and much nicer to look at. Tried the AC level 1s for grins as they were so inexpensive, and did not like the sound. Upgraded to AU24 Se's with Audience and sound was great. Whole system actually. Tried the new AC digital ICs and they were very good. Took leap of faith and bought AC level 6.2 interconnects and level 5 speaker cables. For me, better and more holographic sound that the Audience cables. So far, I am very happy.
