Do people mostly collect DGG records for music and performance merits rather than sound quality? I have a fairly large collection of DGG, spanning from early tulips to digital in the 1980's. But I have never been impressed by their sonic virtues. They are not necessarily bad, but generally are just mediocre compared to other leading labels. Occasionally one gets something like Bernstein's recording of the complete opera Carmen, which sounds fantastic, but from a sonic perspective, it is so uncharacteristic of DGG. It seems odd that the recording engineers in Hanover were just way behind those at Decca, EMI, or RCA and Mercury. Did they just not care much about sonic qualities but focus more on music instead? But I thought people like Karajan cared a lot about sound, and he had DGG record most of his recordings for decades! But his better-sounding recordings are typically from Decca and some from EMI.
