Any Michael Franks Fans ?

I have been enjoying Michael's music since the 1970's & had the opportunity to see him live on one occasion. As a musician I appreciate his vocal phrasing & I suppose the fact he uses some of the top name jazz musicans on his recording session is one of the reasons I continue to purchase his recordings. My question is, from an audiophile view point, what record/CD do you think have the best sonic qualities.
Thanks! Geno
