Query: The ultimate Wagner orchestral music

I have these CDs for almost 15 years before they became a 2-CD set and still play them regularly. Got to know Wagner from the classical Furtwangler cycle, for many the best Wagner music ever recorded. Although Furtwangler is exceptional I do not think that it can surpass these accounts of Klemperer's Wagner. The sound of my CDs is not that great (something that probably has been fixed in these CDs) but the music is illumining in every instance. If you listen to this Tannhuaser you will understand what I am talking about. The Philharmonia Orchestra under Klemperer works miracles as always. A must have for every music-lover, even if you hate Wagner.
