I've been in this hobby/addiction? for over 20 years, and for many of those years, was making the wrong decisions on how to upgrade my system. It is through being on AN and AC for a number of years and reading many, many posts that I was able to start "dialing in" my system. After a period of time, I started getting a sense of which posters truly were experienced and who's advice/comments were worth noting. Now that I have an excellent amp and dac, the ability to discern differences is so much easier. IIRC, when I got Dave's cables, I auditioned the IC's separately and then his SC's. The combination of both together was an eye (ear)- opener. I enjoy audio a lot, but also don't want to audition tons of stuff over many, many hours and days. So auditioning the IC's and SC's together still makes the most sense to me. There are lots of cable manufacturers out there, on Agon and the web. Based on technical knowledge and good reviews by people whose judgment I now trust, the only 2 worth pursuing in my situation are Dave's and Pete's products. As to a digital cable, I haven't thought about that as much and will make a decision after the IC's and SC's in place.
