"The original power supply is marginal from a capacity standpoint, because thе Mk II draws almost three times the supply current. A new power supply has been developed that has been sonically optimized for the Mk II. It is available in two versions, a basic one that meets the power supply needs and sounds very good ($79), and a deluxe version with AC line filtering and considerably greater capacitive bypassing at the output that sounds better yet ($109)."
What is the available output current of the original power supply, and the required current for the new DAC? By marginal, I assume that the original PS is OK to use for the new board?
