This is the kind of thing I keep telling people. With a really good CIEM (like K10 or 8C among others), the scaling is practically limitless. I don't know if people really believe me. But it's absolutely true! I'm listening to the 8C on a BMC PureDAC right now, through a Toxic Cables Silver Widow balanced cable, and the result is jaw-dropping.
Thank you for making the wait for the Dual-sabre DX90 even harder!
