Easy CD creator 6 Bad Quality converting



I was using Roxio 5 to convert my MP3s to Audio CD ( For playing in Car ), what worked great, almost perfect quality. Then I got muself Roxio 6, used the same settings but quality output is TERRIBLE. No lows, no Highs, no dynamic. Removed it and installed Rosio 5 again what is still my favorite. Does anybody got the same problem ? Where can I find more info and software to make perfect Audio CD’s from my MP3s?
