This article contains links to other articles on this question, including electrical testing or measurements on conductivity and blind testing performed under controlled conditions on speaker cable ranging in price from less than $100 to mucho dinero! There are also links to questions regarding optical, digital coaxial and other types of cables and/or interconnects. As others here have already pointed out, there is no such thing as "the best" speaker cable. If you have GREAT or very acute hearing you may be able (and that's a BIG MAYBE) to detect or sense or convince yourself you can, indeed, hear tiny differences in different bands of cable but not "better", per se. The most important variables are: length, guage and quality of conductors & manufacture.
