It was a few years ago so probably an older model, i guess the person im talking about already expressed his dislike for cdt lmao. I have not heard any good cdt setups ever. If it takes that much work and processing from the start just to barely keep up with equipment costing 1/4 to 1/8 its cost, its not worth it. My massive german silk ct 2 tweets completely **** on es 02s in the clarity, top end sparkle and detail with slight attenuations. They play deeper as well as being waaaaaaaaaaaay louder when need to be. Like can keep up with 150s while the es 02 struggled with 140db
