Aftter few hours of test and desperate by the output, I switched back to the CCA and decided to pass the big test, the one of Bruckner's monuments.
First the 7th Symphony of Bruckner by Karajan and the Wiener Philharmoniker
This symphony has been written with the premonition of the death of Wagner (he died before the achievement of the symphony), and was dedicated to Wagner, with some musical references to Wagner. Apparition of the very big tubas (the wagnerian tubas), which are monsters. These monsters can cover an army of heavy metal groups. Karajan at that time was very ill and was feeling his death coming, but wanted to leave a last testimony of his art and he did... A lot of people testified that Karajan could even hardly move, because of pain.
Karajan has always been very directive a kind of tyrant, and for one time, he did not try to impose his will, but he let the music flow, acting as a catalyst. The result is a miracle... and the tubes gave life to the miracle.
Starting with the Brucknerian fog, string tremolos rising... what a ductility, what a splendour when the Wiener strings are backed by the horns and the woods. I could easily hear the colour of the altos, horns, woods. when the overwhelming tubas at the end of the allegro moderato in the final climax of the movement pushed the music beyond any words, I think I had my hairs rising on my head.
The splendour of the strings colours, the munificence of the brasses in the Adagio's climax is out of this planet. With the impression of being able to touch the sound! All is there, basses well kept and not invading or hiding the mids, trebles like old golds, I never heard such a fever, the whole room is vibrating and when the orchestra stops, you still hear some air vibrations vanishing.
I have been stucked for over one hour, I could not leave my attention of what I was hearing : greatness in all its splendour.
So if someone is asking are these tubes worth, my answer will be immediate: "more than that", because these rare moments are the salt of life (my testimony is made upon a certain setup and could be only valid for that setup). Let's turn now to the 8th symphony, still with the Wiener but this time with Boulez (Bruckner and Boulez are like water and fire, but sometimes miracles happen...
and I will not bother you with this one).
