What is the best Frank Sinatra CD?

I am looking for that sonically definitive Frank Sinatra CD?


Sinatra's voice sounded at its best in the 1950's on Capitol records with Nelson Riddle conducting. With that said ... for pensive Sinatra at its best, go with "In the Wee Small Hours of the Morning." For swinging Sinatra at its best, go with "Songs for Swingin' Lovers."
Honorable Mention goes to "A Swingin' Affair" ... getting the brass fanfare right will be a real test for your amps & speakers.

My favorite Sinatra album is Francis A. & Edward K. The remastered cd is very nice sounding and if you can find the vinyl it is exceptional. By the way Edward K is Duke Ellington.
Even though I own the three-cd set "The Capitol Years", listening to Frank on anything but vinyl somehow seems wrong. I own many Sinatra lps and the Jobim is very good as someone else mentioned and is available new.
Duets 1 and 2 . Although he is not singing alone , the band behind him sounds superb.
