I agree with Tvad. It really depends on how one make the cable and terminate the cable properly. I prefer Eichmann Silver Bullet over the copper version because it sounded more open, smoother overall and less harsh in the high frequency. As far as Nextgen goes, never tried them ( since I'm already satisfied with Eichmann silver bullet for lower price) but I do own WBT 0201Es and binding posts and they're superb with imaging and overall balance.
The best part about WBTs is its unmatched build quality.
