Look, I'm not saying that damping is BS. I'm not saying that good engineering practices are BS. I'm not saying that scientific measurements are BS. Nor am I saying that I have golden ears or that I would generally survive a double-blind test of much of my gear. But if there is anything in this hobby that I am confident in, after trying dozens and dozens of amps and headphones, it is that the HD600 and Crack are an outstanding combination, fully the equal (in terms of delivering pure pleasure) to many, many combinations costing thousands more. I'm not claiming that it will yield the best test results in the lab, but in terms of musicality AND detail AND bass AND sparkle AND mids AND PRAT AND speed, the only thing better that I've experienced is the HD800s + Crack, or the HE-6 + certain select amps.
An amp is a total package. One can have excellent damping but fall flat elsewhere. The HE-6 is tough to drive because it has an efficiency of only 83.5 dB.
All of this engineering can be tough to swallow for the lay person. Audiophiles are passionate about their gear and the pursuit of best sound and are susceptible to subjective perception and the stories that circulate. Companies like Monster love to take advantage of this.
