So, the X3 drives these well? I'm considering getting them since i have the S400 (i actually have two...) and was gratefully surprised. They have around 650+ hours of burn-in, so i know the CNT drivers take a lot of time to "set", and i'm willing to wait for the sound to pop up. I was considering driving these with my DX50 for outdoor use and maybe an O2+ODAC for my laptop (maybe, since i haven't bought it yet...). Would you say that they'd sound efficiently with the DX50 in the mean time, or should i drive them with a more powerful source for the burn-in period? (to my ears, the DX50 has a little more juice than the X3, but then again, i only tested the X3 around 3 or 4 days).
Thanks in advance for the response...
