I think you may be mixing a few posts together. I think the original post in the thread related to if cables have a burn-in period, then do they have a life span? (1,000 hours was probably chosen randomly to illustrate the point). At no point did any person or company -- including DH Labs -- say you should replace cables every 1,000 hours. So in answer to your question, DH labs' input is totally valid for this discussion. What's wrong with asking the experts? I did not ask them about THEIR cables nor did I ask if their cables need to be replaced after x hours of use. It was just a general question about the effects of copper oxidation in audio cable. I could have asked the same question to any audio cable manufacturer. So using the car analogy, it was more like calling and asking about catalytic converters not the strengths and weaknesses of specific make/models. And FWIW, DH Labs is one of the few manufacturers out there that don't try to rip people off with insanely priced cable (some of their cables retail for as low as $1.00 per ft.). They have a pretty big following in the DIYer community for this reason and you can order most of their products in bulk and terminate them yourself. -- Videodrome Two-channel System: SB3, into Musiland MD-10 DAC; Outlaw 970 Pre/Pro; McCormack DNA-125 amplifier; Quad 11L speakers; Sota Sapphire ttbl. w/ Grado Ref.
