What is the best sounding Mahler symphony cycle?

Has Mariss Jansons with the RCO been mentioned? I’m listening to the #2 live recording and the sonics are excellent. Not the most powerful rendition, but every detail by the Concertgebouw is heard with no harshness and with plenty of air and space defining the soundstage. The instruments and venue are well mic’d and provide 3 dimensional sound.
In hires it’s a most enjoyable experience.

   I really respect Jansons (R.I.P.) as a builder and maintaner of terrific Orchestras, namely the Concertgebouw and the Bavarians.  However I don’t care for his Mahler.  Sonically, agreed, wonderful stuff.  My issues is that he reminds me of a dog walker that needs to arrive at a destination but is delayed by his dog sniffing everything along the path.  He tends to beautify the micro moments and loses the structure.  His Bruckner is a bigger mess for that reason 

@mahler123, I agree with your impression. He’s not much of a Mahlerian. It sounds restrained and never really peaks.
I’ve been listening on Qobuz, most recently #6 which I would call dull.
Superior quality recordings on the RCO label. I need to have a listen to other recordings in their catalogue.

I have the Jansons 5.  I am not a fan of 5, and don't listen much.  The Jansons is my favorite of those I own.  It is a beautiful recording and adequate performance I suppose, but take that with a grain of salt since 5 is near the bottom of my Mahler list.  I bought it based on a favorable review, but I don't recall who reviewed it. 

Brownsfan,

Just curious,
What are your favorites?
