I'm in exactly the same boat. The composers you listed are enjoyable, and of them, I give most of my time to Beethoven and Respighi, and occasionally Schubert and Schumann.
I also enjoy Mozart (particularly his symphonies and chamber music), Brahms (thunderously beautiful), Vivaldi and Holst's The Planets
. I've also started listening to Berwald (sy. 2 & 4), thanks to recommendation from this site.
Bach is probably my favorite composer. Such a wide catalog, but I never grow tired of The Brandenburg Concertos
. Every piece is an unbroken, flowing stream of beauty. BWV 1050: Allegro is hypnotizing.
Tchaikovsky and Shostakovich don't seem to be well-received around here, and are largely viewed as "background music", which is a fair assessment. I still enjoy them, particularly Tchaikovsky's 1812 Overture and Shostakovich's 5th Symphony.
I've never heard of Gustav Faure. That wouldn't be this fellow, would it?http://www.anus.com/metal/hall/index.php/topic,2295.0.html
If not, could you give me a little more information? Google isn't of much help.
