i would second discovery... i havent heard the signature but i have heard the plus 4 and essence in my system. they can be had at factory direct for very good prices and even better used.
they are on the warm side of neutral and allow the detail to come through and image well ( very unusual they are this well balanced- most warm cables obscure detail and dont image well - the cardas golden cross does this imo)
hope this helps,
mike
