Please allow me to suggest Audio Note Lexus. They are all copper with a very elaborate topology (same as the AN Sogon, which is all silver and costs several $1000), and they sound great. Best of all they are not that expensive: the ICs are about $175 per meter.
I also love the Nirvana S-L ICs which cost much more, and are a hair warmer.
