It seems that Synergistic Research cables are not available in Europe. I have had Valhalla, Townshend, Indra, IsoClean, FIM, and several others that I cannot name in my system and the new Tesla series from SR were clearly better. They are all charged cables. At the last CES a dealer friend and I heard a demonstration of the Odin versus the Valhalla. After we left the demonstration we both said we preferred the Valhalla. But the demonstrator just presumed that everyone preferred the Odins.
I wonder what it is within the Argentos that might lead to them being excellent. They just seem to be high purity 5 nines silver with nice looking RCA and pc plugs.
Certainly at least first off I am going to be using the SR cables on my Tidal Contrivas.
