What cables to replace Highwire's with?


I really like my Highwire 700's. However, I am wandering what would be a substantial upgrade to them. I have a full set-up of these wires...phono cable, interconnect and two speaker cables per speaker for true bi-wire.
I would want to replace all the cables with similar set-up. Please don't tell me about an upgrade if you haven't heard the Highwires.. I replaced all Cardas wires with these and never looked back. However,they are getting old now and I wander what would be a suitable upgrade?

Thanks for the Skywire suggestion. I think that they may be a little too
like what I already have. I would like to see if there are any cables that are
truly a BIG step-up from the Highwire's. Thinking maybe Kubala's
or Siltech or? Haven't heard these in comparison so not sure.
Spending more money does not necessarily give you an equivalent cost/benefit sound improvement. Try cables from people that offer trial periods so you can compare and evaluate. Some that I have had good experiences with are Grover Huffman, Chimera Labs, Ridge Street Audio, and Morrow Audio. Lots of others out there.
