Nah, that's just to show you how much more complicated is the X5's design next to the X3's. And that PCM1792A is nice and is the the best TI DAC chip on the market. I'm sure they've done their homework and its implementation will be top-notch.
Well there are a few things I like about it not the dac though but again I might be proven wrong. The wheel is one of the features I like and the 2 sd card readers for ample storage if I am not mistaken does it come with 128gb internal ram or less?
What's the expected list price?
