Question for recording artist/engineers

Let's say you have a jazz band who wants to sell cds of their music with the best quality of sound they can achieve at the lowest out-sourced cost or do-it-yourself. If one wants to do a just-in-time type of manufacturing of their cd, how can they improve things?

Currently they are recording at 48k in Pro-tools, mastered in Sonic Solutions by Air Show Mastering, and then they use top of the line cds (Taiyo Yuden) with a Microboards Orbit II Duplicator. This has produced average cds but we want to do better.

What would you engineers do to improve this so it gets closer to audiophile quality? Would you recommend using a different mastering house, different cds, or a different Duplicator? Or would you just bite the money bullet and go directly to a full-scale manufacturer? We are trying not to have that much money tied up in inventory.

If this is the wrong place to post this question, please suggest another message board to post.

Thank you for your feedback and assistance.
