I used the TMC Yellow Label to connect my B&K Ref. 10 preamp to a B&K AV6000 power amp for about 4 months. Since then I have audtioned the Wireworld Equinox III+, Nordost Blue Heaven, and Audioquest Viper; all in the $150 - $199 per meter price point. I found them all very similar in terms of presentation i.e. somewhat too forward for my tastes. The TMC Yellow Label was more laid back but the bass was a little too heavy. Detail was good and the mid-range was nice and full. Their claims of besting more expensive cables are exagerated. Instead, I found them to be the equal of cables such as those I mentioned. Cables are very system dependent and should be audtioned before making any decisions.
