Using female RCA barrel connectors, I’ve connected both IC’s in series. This blend offers the best of both – with slightly less of each’s character. It has the speed & articulation of the WyWires Gold and the rich flavor of the Teo GC’s. So far, so good. Without the GC’s in my system, on certain recordings, female vocalists were slightly grainy on their high notes. With the combo IC’s, their high notes are smooth and sweet. Yet, the bite of the percussion remained. Curiously, the sound changes depending which IC is positioned first in the combo series. These observations are with my tube preamp and Class A SS amp, If I were to substitute in my Class A tube monoblocks, I’d probably just use the WyWires Golds by themselves.
I definitely recommend trying them. Can’t go wrong with Teo’s generous return policy. Synergy is different for each system. Tommylion - I have Audio Note Lexus speaker cables - but, really can’t compare them to IC’s.
