John Knowles Paine (1839-1906), was a member of the "Boston Six", which included George Chadwick, Horatio Parker, Arthur Foote, Edward MacDowell, and Amy Beach. The music of Foote, Chadwick and Beach has been discussed in Unsung threads on several occasions, and is well worth hearing. I'm especially fond of Foote's chamber music, which is very good indeed. However, I don't remember any of them being compared to Beethoven. That was reserved for Knowles, who was on the Harvard faculty.
Of knowles' orchestral works, there are CDs available that include:
Symphony No. 1 in C minor, op. 23
Symphony #2 in A major "In Spring" op. 34
along with some overtures and preludes for orchestra
Also a Mass and assorted organ works are available on CD, although I've not heard them. The symphonies are not Beethoven, just as Herzogenberg is not Brahms, but they are still good listening.
