@dbt Cool, thanks for sharing. The Boomslang was one I was considering trying. I assume you know about Audio Bacon's review?- he loved it- it was the BNC not AES, but should be similar findings. He did state something to the fact that is wasn't the most transparent though, some quotes below:
"So the first thing I noticed about this cable was how natural voices and instruments were presented. It didn’t exude “atmosphere” or “clarity” but it sounded raw, accurate, and unadulterated. In fact, this is the rawest sounding cable I’ve heard so far. It’s a very good thing. It’s also the cable that has rid me of the notion of how silver is supposed to sound. Along with the WAVE Storm Reference, this is one of the warmest sounding BNC cables I’ve reviewed so far. Both of which are made with 5N silver.....
- Although the tradeoff for a richer sound is a less present treble, this isn’t the case with the Boomslang. It’s still able to allow cymbals and strings to shine appropriately.
- It’s not as quiet, treble present, speedy, or as resolving of the lower level details – but from a musicality standpoint, I feel it provides enough of those qualities.
- Not the most outwardly “dimensional” and “outlined” sound. Some reverb, reflections, and decays aren’t made as apparent – but are still very audible."
Just goes to show one has to try themselves. I wish I could add something regarding a AZ cables comparison but just had some older Transparent speaker cables and XLR's before them.
