on reading someone's profile, but this had gone through my mind before-
if someone were to ask me (or if I just wanted to suggest, to be less prideful about it- I believe in ego, I'm less pleased about pride, some other time on that) - where next in classical music- of course that depends on where from, on tastes in general...
there are a few composers after Bach, Beethoven, Mozart, Haydn, Brahms, Vivaldi, say I'm tempted to recommend though. For instance if you don't know Fauré's (Gabriel Fauré, 1845-1924) chamber music, his violin sonatas, cello sonatas, piano quartets and quintets, etc. - I think you're missing out on something here.
(The list of works I've heard in live concert is not really long, especially since I've attended very few in the last... five years? more!... - but I've had the pleasure of catching two of these works, one of Fauré's violin sonatas and one of his piano quartets - quartets for piano, violin, viola and cello, before anyone asks... the sonata back in college, the quartet more recently, the two works themselves written at almost the same time (the sonata written 1875-6, and the quartet written 1876-9 but revised until 1883. I note in some confusion that the composer was thirty when he began the sonata, one of his more popular works- the number of recordings, for one thing, is ... a lot. Though if he's really known at all "outside of some circles" it's by his Requiem, and back when, I practiced a viola arrangement of his lovely song Apres un Rêve - probably a viola arrangement of cellist Pablo Casals' cello arrangement... (the song is from 1877- finished earlier than the quartet, but not the sonata... oh. I assumed that since it had opus 7 instead of opus 13 - like the sonata - or 15 - like the quartet - that it was rather earlier; but the sonata is actually an earlier work. I do remember, I think, that he had trouble getting the sonata published! But not for lack of spirit and beauty- and singing melody... the music from toward the end of his life- the 2nd violin sonata from around 1917, the two cello sonatas (1917, 1921), the piano trio... tends to wind around and be harder to follow, except for the finales, which, with dramatic instinct ;), he always makes hell-for-leather by comparison, rather like Vierne in his quintet see-last-post; but ... they have their fans too, me among them...)
There's a few places on the web to hear a work or two of his for free (classicalarchives.com comes to mind, I think?) at least in MIDI, possibly in live performances also.
