I have tried Audioquest Clear, Straightwire Serenade & Virtuoso and Audience AU24 with planar speakers and EAD preamp/amp. The Clear is nice, the Serenade has a nice warm sound but does not excel, the Virtuoso is very system dependent, harsh with my old preamp/amp combo but with the EAD it has great bass & resolution. The Audince is my favorite cable, crystalline highs & very musical.
