@v-fi I agree with your thoughts on Iconoclast and that an in home trial is the only way to really know what is going to be best in my system. I should look into the details of an in home trial with the brands I mentioned and possibly others. Given the high cost of some of those cables, I am not sure if it is possible to get multiple in for audition at the same time from a place like the CableCo. The other point I have been thinking about is that a free home trial also locks me into buying new at retail price. Not a deal breaker, but I like the idea of saving some money with used interconnects where returns aren't going to happen.
@kennymacc Undoubtedly, the Thunderbirds are excellent. I have used AQ Fire and Earth XLRs for some time so I feel like the Thunderbirds would be a natural progression, but it could also be fun to try something completely new. I see LTA is often paired with Cardas at shows, so that seems like another possibility. I have also previously owned speaker cables and power conditioners from Audience that were nice.
@zlone did you stick with the AZ Matrix Ref's in your Audionet setup? I believe you were thinking about replacing them in another thread, but I didn't see how that ended. I might be in a similar situation in that I can't say anything bad about my current RCAs, but just wondering if it is possible to achieve even better synergy and improve on what I already think is a pretty engaging sound.
