DAC Output Stage - order placed!

Hi Brian,

I ordered the kit today, I decided on (1) UTS.
It was going to be tough to shoehorn two of those modules in there anyway... :-)

The only thing to clarify is the wiring between the DAC chip and the module, let's see if I've got this close:

DAC pin 26 (L-) to UTS terminal 'in L'
DAC pin 25 (L+) to 22 ohm resistor, resistor to GND
DAC pin 18 (R-) to UTS terminal 'in R'
DAC pin 17 (R+) to 22 ohm resistor, resistor to GND

In the Denon schematic, all four AGND pins (16, 19, 24, 27) are tied together....this will be my analog ground, correct?
If correct, let's call this GND.

GND to UTS terminal 'Gnd L'
GND to UTS terminal 'Gnd R'
GND to UTS terminal 'Vcom L'
GND to UTS terminal 'Vcom R'

So far so good?

The schematic on page 22 of the manual shows (4) 51 ohm resistors.
What do I do about those?

I could locate the 22 ohm resistors close to the DAC chip, or I could mount them somewhere on the UTS....which is preferred?

Thanks,

Mike
