I very much enjoy Wagner as well especially the Wagner without words. I like the big brass instrumentals without the interference of opera voices.
Not being a big opera fan, I mostly agree - I wish Wagner had written symphonies instead, as he's unmatched when it comes to creative harmonies and orchestral color. I mostly listen to the overtures and preludes, or to orchestral arrangements of the vocal music (Leopold Stokowsky made some great arrangements of opera excerpts for orchestra).
I have the Ring with out words and his overtures and preludes without words. It is simply amazing.
Wagner really should have hired a competent librettist.
