I have Innersound Eros MKII wich I dont actually have in my set up anymore, but when I changed the crappy stock cords to Tekline power cables (Eclipse) it made a nice improovement, trust your own ears, these cords were had for $50.00 I think they normally list for $150.00 so dont get fooled into super expensive cords, atleast without serious and money back audition.
