I am in the same boat. I want to build a pc for my DAC and was thinking of the NEP-3002 or the Tunami, both being Ohno type copper wires. From various comments I have heard the Neotech can be very smooth with black background. What Furutech ends did you use? I think the consensus is that gold plated terminations may be a touch warm (if you use them). Amps usually need unshielded cables. I am using a MAC-HC pc for my amp with great results (unshielded) but want to try to build my own pc for the DAC as a project.
Please let us know how your cables sound after some burn in time.
Cheers,
