It’s a very broad topic.  Internet Radio probably offers stations that specialize in chamber music as a practical way to explore.  Most of these chamber works greatest hits have many recordings, most of which I haven’t heard
Mozart Clarinet Quintet- dozens of recordings but try one with Martin Frost on the BIS label for  superb sonicsÂ
Schubert-Trout Quintet  I like the Marlboro recording with Rudolph Serkin
Beethoven String Quartets I would start with the Middle Quartets (Razumovsky, Harp, Serioso). My favorite is hard to find; the Tackacz Quartet is a good alternativeÂ
Beethoven Archduke Trio- the Sitkovisky Trio again on BIS
Brahms- Clarinet Trio and Quintet-Frost on BIS again
Schumann-Piano Quintet-Leon Fleischer and the Juliards
Franck-Violin Sonata-Perlman-Azhkenazy
Janacek String Quartet-s-Mandelring Quartet, because it adds an alternate recording of the second with Viola de Amore
Shostakovich-Eight SQ-Borodin QuartetÂ
Shostakovich Piano Trio #2 Stern-Rose-Ma
Bartok-String Quartet s-EmersonsÂ
Bach-Solo Violin Sonatas and Partitas-Nathan Milstein
Corelli-Violin Sonatas. Manze
Debussy Sonatas Boston Chamber Players
I could be doing this all day and these choices barely scratch the surfaceÂ
