Lacee: The Tetras?? Nice!!! I once had them for about 6 months (I reviewed them) and they were some nice speakers. I know John Atkinson panned them for the technical aspects, but with the Shunyatas and the First Sound and Hurricanes (but Nordost interconnects at the time [2004]), that was one helluva nice sound. The microdyamics on voice were far better than my Hale Revelation 3s and pretty mesmerizing. And that was with first generation Shunyata power cords! I never understood why they didn't make a bigger impact in the market: they are terrific speakers, with a very low noise floor, and very 3D in their imaging. With Black Mambas, or Pythons, they should be knockouts.
And the bass on my Black Mamba, now that it's broken in (pluggged it in to the wall using a line conditioner I had lying around and then the refrigerator in the basement AND the freezer to really speed up the break-in), it's a GREAT cord. The highs are very pure, much purer than I remember the earlier Shunyatas being, and I still have a Taipan Helix cord on hand, although traditionally, I've used Pythons. The bass impact and clarity is excellent.
