Hi @jzzmusician, I am in the same boat and age. However, the DAC I'm using now, Geek Out 1000, will handle PCM up to 384 and DSD256 so the few files I have in those formats play fine in my system.
As itchy as I am, I am waiting a bit longer to see if Tidal offers any music that is MQA as they have promised. Even if its only a few titles by this autumn, I will then acquire an MQA capable DAC.
If no Tidal content is available by autumn that is MQA, then I will probably acquire a DAC capable of DSD 256. In addition, it will need a decent headphone outphone and must be remote controlled - the DAC will also have an input from my TVs Toslink out. I am thinking Mytek Brooklyn.
I wish the Schiit was remote controlled and DSD capable. I haven't ruled out a PS Audio Directstream or Directstream Jr.
I really like the quality of sound of DSD on the few albums I own so I imagine I will be acquiring a select few from my future purchases.
If I had any one of the three DACs you listed in my system right now, I would probably stand pat - except for the remote control aspect of the Schiit.
