jafant,
I've had the Vovox in and out of my system over the past few weeks. I haven't decided if I want to live long-term with the smoothness of the Cardas Clear Reflection or the sparkle of the Vovox Sonorus interconnects. When I have time to listen carefully, I'm going to try the Vovox between my DAC and preamp instead of between the preamp and amps to see how that changes the sound.
For digital signal handling, I had been running a DH Labs USB cable from the Innuos Phoenix to the DAC, but I recently replaced the DH Labs with a Network Acoustics USB Cable III. The new NA USB sounds a bit more open and clear than the DH Labs USB without sounding as bright. I'm still running a Shunyata Alpha USB from the Innuos Zen Mk3 to the Phoenix, but I may switch the two USB cables around to see if the sound changes in a way that sounds even more musical.
I continue to be surprised at how much the sound of my system can change with just a little bit of cable shuffling.
I hope you're making progress in your cable search.
