Thanks for sharing. Glad you found great cables.
Strange however, I have never heard anyone find Cardas Clear... in any version described as fatiguing. I have spent a lot of time with many different Cardas cables over decades, all the Clears, and they are always warm in different amounts and musical, never harsh. My first thought was perhaps it was your components but I am very familiar with the Pass integrated and the Aurender N20... neither are harsh or fatiguing. Strange.
