Like most things in audio, the biggest bang for the buck begins by moving above minimum quality. In this case the stock cord is the minimum quality.
Almost any of the power cords discussed and sold at Audiogon will help your sound. As for money, you can spend as little or as much as you can stand.
The Jolida is a fine unit, but since it retails for about $1100.00, that extra $400.00 is a fairly high investment. I would start with used, maybe a Purist or Cardas.
I just took a look at classified here at Audiogon and saw a Cardas Hexlink power cord for $75.00. If this or another similarly priced (used) cord does not suit you, your likely to be able to resell for very little or no loss.
