Entry levels ICs for Classe gear

I've just purchased a new ESOTERIC SA-60 and used Classe CA-2100/CP-500 from here on Audiogon.. I haven't purchased my speakers yet, but likely to be DALI HELICON/Euphonia towers. What are the recommendations for a decent entry level IC (BALANCED/XLR). I see several types.. SIGNAL CABLE/Copper vs. Silver wiring/Cardas/Audioquest but the specs mean nothing to me. The system is being placed in an AUDIAV custom rack.. so IC connections will be short.
Thanks ahead
