jafant,
I don't know whether I will try a full loom of Vovox at this point. If I do decide to get a 5-meter pair of Vovox Sonorus interconnects to make the change to a "longer XLR - shorter speaker cable" set-up, I will then have my current 1m Vovox XLRs to try between DAC and preamp, combined with new 5m Vovox XLRs between preamp and amps. If that arrangement sounds better than the Cardas-Vovox combination I'm using now, I will eventually go that route. For now, I'm going to live with the combo XLRs for a while to be sure that works for me long-term. I have heard that the Vovox XLRs don't change in sound much between shorter and longer lengths, so I'm assuming the 1m Vovox will have the same sound signature as a 5m Vovox. I haven't tried any other Vovox wire so I don't know how their power cables, speaker cables, etc. would sound in my system.
In my reading of pro audio forums, I have seen a few comments that support the use of Vovox Sonorus interconnects selectively rather than at all stages of the recording/mastering process. I guess some users think that the clarity and openness of the Vovox can be "too much of a good thing" when used throughout the process. On the other hand, some users have wired their entire studios with Vovox and rave about how "live" it sounds. I know that Tom Thiel really likes Vovox Sonorus as a mic cable in recordings he has made.
I mentioned earlier that Vovox has a more expensive cable line (called Excelsus). They also have a less expensive line called Link. All three lines (Link, Sonorus, and Excelsus) include both shielded and unshielded cables. The unshielded cables tend to sound better as long as extensive noise rejection is not needed.
