Time to retire my McCormack DAC-1 ?

Thank You tvad,
 I will call SMc tomorrow.
I was looking at the Schiit and was very impressed. A friend has the tube active/passive pre-amp
and I am duly impressed with it's sound and build quality. She upgraded it with a NOS Foton Soviet era tube.

What sound characteristics are most important to you and what would you like to improve upon?  Lots of good DACs out there, so a lot depends on what type of sound you’re looking for. 

The McCormack is ( to my ears) deep and open. My issue is the future. I have tried to keep the PC out of my HIFI but reception became a problem for me and I ended up replacing my Magnum Dynalab tuner with a internet tuner, which I love.
I am listening to a "station" from the Arctic Circle as I write this (77 degrees latitude!)

The McCormack couldn't read the tuners output signal and it has opened up this new can of worms.

I have a good SACD player but that format is going the way of the Dodo so I need something that can handle all the different formats and rates  out there with the nice big open sound I have gotten from my DAC-1 for the last (gasp) 25 years!
Oh yes used I'd like to keep the price at around a grand used. Am I asking too much??

@OP,
Schiit offers a wide range of DAC's at various price points, but the Gungnir and Yggy are second and highest priced models and perform beyond their price point.
My choice is the Ayre Codex, which you can find used near $1K, sometimes below. And, customer service-as with Schiit, is very good.

You might want to check out the Bluesound Node. You don't need the latest model, so buying used is available. I was just looking at the offerings and it has Tune In- which has radio stations around the world.
You can either use the built in DAC in the Bluesound or output to a separate DAC, like the Codex, and get high quality sound along with a wide range of music services.
