I see a lot of comment so far, but no direct recomendation?'Cause it's really impossible. What you find acceptable price-wise and sound-wise may or may not be in line with anyone's suggestion.

The cheapest acceptable cord is the stock cord included with Pass Labs, as others have mentioned.
Aftermarket cords may offer marginal improvements.
Even the Purist Audio Dominus are not significantly better than the Pass stock cords...though the Dominus are somewhat better in the bass and treble, but at a much higher cost.
On the other hand, it's ironic that anyone willing to spend the premium required for Pass Labs amps is quibbling over the cost of power cords.
It shows that everyone has specific price/value points for different elements of their systems. There's no right answer.
