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 really like a version of the Mahler 9th conducted by Blomstedt but it is not comercially available as I recorded it form a BBC Radio 3 broadcast and to me it is devine with all I ever want from a Mahler symphony , it has wonderful dynamics , extreme pathos and a vulnerabillity you can only get from Mahler and it is conducted by a man who the audience and orchestra love.
I never heard any Blomstedt Mahler; I just assumed it wasn’t in his repertoire 
I am listening to the Blomstedt Ninth on Qobuz now so it must be available?
Just finished III; so far it’s excellent 
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.
