just a heads up, take advantage of their 30 day return policy. these are some of the best cables i have had in my system. i am in the process of writing a review on them along with another reviewer for stereomojo. i will be doing the entry level planus I (copper) speaker cables and planus Cu (copper) interconnects. the other reviewer will be doing the more expensive planus II speaker cables (silver) and planus Ag (silver) interconnects.
