Portable:
1G Shuffle - $50
New Super.fi 5 - $170
Home:
MAC mini - $500
Assemblage DAC-1: $250 (same specs Sonic Frontiers TransDAC, a little rare)
Mods for Dac: $200
M^3 amplifier: $170
HD650 - $250 after rebate
Total:$1590... Ok, so I'm not cheap. This is not the best as a financially concerned person's hobby.

Most of you obviously have a computer anyway, subtract $500. Add in $100 for the BJ cables.
