What is the best sounding Mahler symphony cycle?


Folks... I love Mahler but my two versions of the 5th sound very low-fi. I am looking for a well --- really well --- recorded 5th on redbook CD --- or better still... a whole mahler symphony cycle that is audiophile (or... near audiophile quality.

Any help would be appreciated

I had ordered Fisher/Budapest M1 and I have to concur with the naysayers here.  It’s nicely played but in a ridiculously crowded field it doesn’t offer much that is new.
@mahler123If you are not impressed by Fischer's Mahler No 1 why don't you try his No 4 as this one is at the moment my favourite but stream it before you buy it as I hate to see people left with a CD that they now have as a coaster.

  I assume that you mean Ivan Fischer and Budapest.  I like their Fourthand I’ve been comparing it with the Blu Ray of Ivan Fischer leading the Concertgebouw.  They are very similar
@mahler123   Yes I did mean the Budapest band I find they are very light with the symphony which Mahler implied through Bruno Walter and the soprano they chose is suitably childlike in the last movement instead of the gargantuan warblers that some past conductors have chosen.
Yeah, their Fourth is a keeper.  Started listening to their Sixth today but haven’t formed an opinion yet
