Trying to choose between 3 DAC's

I need a new DAC and I could use some guidance. I wish I could audition all of these before buying, but I am unable to, so I'd like to hear some of your opinions. So far these are my top 3 (in no order):

1) Musical Fidelity M1-A DAC
2) Schiit Gungnir
3) Music Hall 25.3

I'm using a Rogue Audio Cronus Magnum integrated tube amp, and Totem Rainmaker speakers. The third DAC I've listed is a bit older than the first two so I'm not sure if it really contends, but I was able to listen to it and it sounded somewhat nice to my ears (it's also a tube dac). I'd entertain other suggestions for DACs in this price range if you have any. My concerns include finding one with up-to-date digital components (async usb, 24bit/192khz input), good psu/analog output, and it must be able to handle usb,optical, and dig coax inputs. Thanks in advance.
