Enhancements include modern DAC and ADC with much lower noise floor, SPDIF output and unlike original DB60XG with 16bit output this module has 18bit output like DB50XG. SPDIF output can be either 16 or 18bit, depending on what side the small resistor network is put to. The analog section is also redone, giving option to follow same EQ curve as original module or flat output (SPDIF only has flat output), also gain is also set just high enough that it will not clip inputs of any existing sound card, unlike DB60XG which pushes 8Vpp out that clips any existing card.
I have also put the components on the side that faces the host card so it would fit better between other cards, original DB60XG module tends to have its components touch the neighboring card which can result in disaster :
There's 4x PCBs left of the revision with 18bit output and 8x of the earlier version that lacks 16bit output. I won't sell any full cards, I only offer service to put your donor module (XR385 or XR712)onto the enhanced board with all the new parts needed. Prime candidates are modules that have mysteriously gone silent, the terrible ADC+DAC chip on them tends to fail for some reason. Both my modules went silent due to the chip dying one day.
DB50XG is not a suitable donor because its program ROM enables DAC output mode that cannot be easily adapted to what modern parts use. I will not be burning the program ROM of DB60XG to use instead due to illegality of that and due to program ROM differences, external modules aren't usable either even if most other parts are same.
I'll provide some recordings later, I am half busy with preparing to move. I have finally found a place to move to but it requires lot of cleanups and some renovations first before I can settle in there.
Transplating service is 50€ for new 18bit version and 40 for old 16bit one, plus shipping cost. The move might delay things though.
