I’m looking to upgrade my Magnum Dynalab MD106T???


I am wanting to upgrade my Magnum Dynalab MD106T tuner. It must have balanced outputs and doesn’t need to be a tube tuner. My current MD106T sounds nice but I’m wanting to upgrade. Any advice on a nice tuner to upgrade to would be appreciated. My 106T is nice sounding but I wonder what nicer is out there.

I would look into getting a better antenna before replacing an already excellent tuner.
I doubt very much that the Accuphase would be better. Nowadays there are very few top quality FM broadcasts that would justify paying that much for a tuner. I use a Magnum MD90 with an attic mount yagi type antenna. Save your money, that tuner that you are using is top of the line!
Your “true differential” balanced output requirement will significantly limits your options.  
Other than improve your antennae location/position, the Marantz 10B or the rare REL are the final frontier.  A close second would be  Modaferri modded tubed Macintosh.
