Thank you Paul,
I totally agree. "Stiff" phrases is one of the reasons why I recently bought two of the bigger string bundles, but my Mahler playbacks do not yet benefit from them. They're all done with the special edition, which to my opinion is not to blame. But one of my problems when coping with the SE is the slow attack of some string (and clarinet) legato patches and the fact that the target notes are not looped. So they often had to be replaced by rather unexpressive "sus" patches both for passages needing a clear timing and for very extended notes lasting several bars. So some cantilenas loose their singing character and sound like just “unmusically” added notes. This is a detailed reply to what you write although I can only guess, that you mean the same thing as I do. So there's another self-criticism I have to offer: With Mahler, it sometimes was not easy to find the different gradations of pianissimo in songs, which also have sudden loud eruptions. It is like cutting the legs of a table without a cane. There is always remaining one leg too long. So you correct and correct and at the end there's almost nothing left but the tabletop. By the way: I’ve done the first steps of translating my German-speaking website into English and French.
The Mahler page is the one I began with. So if you like you can visit it, for example to get free access to a video offering much more extended excerpts than the one you know: https://www.uli-schauerte.de/mahler-minus-you-english/
So long
