I can only share what I’ve tried and my thoughts. Started with Blue Jean and entry-ish Wire World interconnects—these were good but not a “wow”. Then made an audible jump to DH Labs Silversonic that delivered a wider listening window and general sense of ease. Last year went to Audio Art Cable Copper Cryo XLRs and, wow, these doubled again the ease, fluidity and openness of my system. Key factors in both DH Labs and AAC purchases were direct queries and discussions with Greg and Rob, respectively, who concisely and helpfully narrowed down what I was looking for and which of their cables could help. I’m happy with the process to get to this point and settled in firmly with the AACs.
