I think they are one the best buys in audio.
Synergy always plays a part in any system, so one guys "wow!" may be another’s "meh.". I don’t try to get caught up in measurements, because typically they are useless-I recall when researching these that one guy in some forum was overly concerned about how much more he had to turn his volume up to get the same sound pressure as his last speaker cables, so the resistance must be really high for the Fidelium’s, who cares! Just use your ears! I have used these on several different amplifiers, on 2 different sets of speakers 85db/2.83v/m and 98db/m, in 2 different rooms, and they sound exquisite in any permutation.
They replaced well regarded cables costing twice what these retail for, and recently I picked up a set of very expensive cables from a highly regarded cable only manufacturer, used price for a 2m set is around 6K, and I am currently going back and forth to determine a preference- undecided.
So yeah, absolutely they still hold their value 6 years later, and probably 10 years from now. I just wish they were more durable for their "connectors", because there are no connectors, although Jeff can re-terminate for a small fee.
