Seriously considering picking this one up. It's either here or the questyle. So many decisions....sigh.
I have the UD-503 paired with the TH900 (w/Lawton pads) using balanced out. It's a great pairing that tightens the low end and smooths out the high end of the TH900. I am using the 8x up sampling, no digital filter option.
