I have the Pangea AC-9 power cord and did try that on the May KTE and liked the Forte F3 better. The May KTE actually generates a fair amount of heat so I don't think a smaller gauge cord like the AC-14 is necessarily appropriate.
@mitch2 I bought the DAC used. The seller simply included the Forte F3 cord.
@jackd I have the Triode Wire Labs Obsession 20 amp cord connecting my Puritan PSM-156 to the outlet and thought it was a nice improvement over the stock cord so I'll take the Digital American II under advisement.
