I think "DACSA" is the obvious choice.......
Now where I have heard this before.... hmm... maybe, me? ;)here....

I like the GK-1.x naming. It sounds modern and works with versioning of future pre-amps. So, if you come out with a new pre-amp that bests the GK-1 design, you've got GK-2, GK-2.1, etc. Consistency is good. I'd give the DACSA a number, too. DACSA 1, DACSA 1.1, etc. to keep up with software/hardware changes down the road. It's not perfect but, it will make it easier to review products down the road....

(Something I still need to do with my AKSA 100-N)
I think if the DAC has a unique technology, using that in the name would be kind of goofy and dated. They did that in the 80's. Please don't call it 'the DACSAbit' or similar.
That's all 2 cents I have.....
