After attending my 50th high school reunion, I trusted Audio Video Workshop with a 50-year-old vinyl recording of my high school concert choir (class of 64!).  Many of my classmates were interested in a digital version of the record, so AV Workshop produced 24 CDs and MP3 versions.  They completed the job in just a few days, and did a marvelous job of cleaning up the inevitable pops and hisses on such an old record.  I received many positive comments from my classmates, commending Audio Visual Workshop for the excellent quality of the CDs and MP3s.
