Have ever you heard the Brahms 3rd and 4th symphonies? There's a not a shred of muddiness in them. The finale of the 4th is spine tingling. Simply beyond compare. And the violin concerto and 2nd piano concerto may be the best in their genre of the 19th century. He's survived all manner of fashion taste and will continue to endure.
Never could get past the first one or two hearings of his symphonies, but I must admit that his violin concerto is pretty good (but then again, I even like Tschaikovsky's violin concerto!).
I will look for the symphonies you mention only because I have so much faith in Freepers...
