Those statements are kind of at odds--aren't they? If Audeze has designed a new generation driver, doesn't it stand to reason that it's superior to the LCD-3 driver? What would be the point of a completely redesigned driver that doesn't sound quite as good as one they already manufacture? Audeze isn't claiming they found a way to increase production and lower costs like HiFiMan did with a simplified HE-400 driver. The LCD-X is close to the same price point as the LCD-3.
"new generation" are your words.....
The HE-500s are a "new generation" with more efficient drivers compared to the HE-6s...but yet the HE-6s are still the better headphones.
