That’s a kinda neat idea - 80 or 123 or thereabouts CDs is a good start..
I consulted amazon which have both Warner and one with Decca/Deutsche Gramophon logos on it - read the reviews there from people who purchased and (hopefully) listened. I generally see high praise from those who are not necessarily seeking the very very best.
One reviewer was a little underwhelmed (Decca) after having absorbed the aesthetics of the Mozart and Bach box sets. Or, "box too large". First world problems in the extreme. Must be thirsty work.
