What is the best sounding Mahler symphony cycle?

Best sounding Mahler cycle? It is a question very difficult
to answer.

Since Haitink is mentioned here, should Kubelik, Tennstedt,
Sinopoli and Boulez be nominated for a fair comparison?

Also for East European interpretations, there are cycles of
Neumann and Kondrashin available.

Happy Listening!

Wow! I don't know the comment can be this definite ("....none of the ones....") and critical in this forum. For a person posted more than 1850 answers in all categories, the person must be extremely knowledgeable.

Please discard my naive suggestion.

But it is nice to see Newbee and Brownsfan are here.

Let me retire from this conversation. Excuse me!
