Pristine Jazz

I've been into jazz these past 10 years. While, certainly not an expert, I have amassed a pretty good listening selection. (Tatum, Parker, Davis, Coltrane, Adderley, Evans,Peterson, etc. etc.) I love what I have, but the recordings are just not of the sonic quality (how can they be, given the time when many were recorded) that we're capable of today. Now here's my question: Can you give me some killer, pristine, sonic wonder, jazz recordings, (with performances to match, of course) that do it for you. Thanks in advance. You guys haven't steered me wrong yet

P.S. Upon your recommendations I bought some female recordings by Eva Cassidy, Warnes, McKennitt, Barber, etc. Wow! I forgot how wonderful a properly miked, beautifully recorded CD can sound. My system just rocked me, more than usual. I just want to experience this with jazz, too.
