ALEX, this thread is becoming hotter than You KnoWhat! Time for me to go and take a very long icycold shower, lest I perform some embarrassing act over the phone, involving colorful plastic cards and authorization codes, wich I may regret after eventual spousal disclosure!!!
Will you send an evaluation unit of the moded DV50 to SMILIN eventually?
I'd be curious to know why you ordered UX-3 instead of X-03 to modify: X-03 is more of a purely audio device.
Furthermore, If I remember correctly these new units may support an external DAC directly, as well as an external word clock. You might be able to perform your magic by connecting purely external boxes, which in turn would likely also be compatible with X-01.
