My experience with Harmonic Tech is similar to Lev335's. They do a disappearing act, but not before you notice that they are equally balanced over the entire frequency range. This means that in a bright system you may notice a fuller bass, and in a warm system you might find more detail in the highs, so if you don't have the opportunity to try both in your system, you might as well go for the H.Tech's because of the savings. It is clear they are both very good cables, but like Lev335 the Harmonics won out in my system. By the way, if you listen to the Harmonic Tech "Magic" cable , you will not be satisfied until you own one. I have their Truthlink, and their new Truthlink Silver, which adds a touch of silver to the Truthlink. It is a gorgeous sound, very liquid, but I had their "magic" cable for 2 months, as I was breaking them in for a friend, and now I am looking forward to eventually having a pair of my own. They had absolutely no coloration, and yet it was not blandly neutral, but more "live" than anything I have heard yet, including some cables costing three times as much.
