FWIW on the subject of DG sonics on LP or CD, I have far more objections to the recording when the performance is by Von Karajan, especially on CD, but some of my LP's from the 70's by VK are as bright and glassy as latter CD's. I think he did a lot of fiddling in the recording process as well. Not my fav sonically dispite some of the great Mahler reviews he got for #5, #6 & #9. As Texasdave points out Boulez's recordings on DG are much better, especially his Debussy which I think is pre-eminent performance wise as well.
Mario b, That Solti 8th is one of the great ones. This is also on a new "Legends" Decca CD - the transfer went very well. If you like 'dramatic' Mahler, try some of Solti's other performances. Lots of folks don't care that much for him, but the performances are rarely ever boring and the sound is usually quite good. Try his #1 with the CSO.
