Ihave heard very good things about all their products: lower-priced perform FAR above their cost, and higher-priced are contenders for some of the best at any price.
They are relatively unknown in the USA, and perhaps because of this, I got a great deal on a used pair of Sword speaker cables. VERY smooth yet detailed sound, bettered the Nordost I have heard (SPM, Quatro Fil), as well as Cardas, Ensemble, Zu, and several others in my system.
I'd recommend they be checked out, especially their lower priced cables, or the higher priced ones used.
