I know David Elrod for many years since he was a partner in Electraglide. Every time I compared his power cords to anybody else's his cords were better. Very early model were a bit lean but since introduction of Signature and Statment lines - I can't critisize anything there.
Yet, David Elrod just introduced, a few days ago, new line of "Gold Edition" interconnects and speakers cables and power cords. I was lucky to auditioned his interconnects and they greatly outperformed everything he did before. I don't think he has competitor anywhere in the world.
Member Brainwater is aboslutely right. David takes his time to develop the cable. Two or may be even tree years ago, I have obtained his early speaker cable and it was the best then anything I auditioned before. Still, it took him three years to develop it fully and be is satisfied with his "Gold Edition" cables. I don't know any other in cable business who would take three years before placing his cable in production. While not cheap - its worth it.
