Kleiber on Decca/London would be my first choice too. The sound is not bad -- indeed, the voices on cd sound quite good even though the stageing is not top-notch vs the vinyl (in my system). Solti I find to be very strict to the rules and, though an excellent performance (voices being in the spirit of Sugarbrie's post), I prefer Kleiber's for being closer to the "nature" of the story.
