If you can find a used Cary 100t DAC, it is a great unit. Probably in the $1k - 1,100 range.
If you have a local Cary dealer, reach out to them and see if they can help you find 1.
Did not have a sales cycle since Cary introduced the 200t quickly behind it for DSD capability.
The 100t uses the 6922 variant and the Russian equivalents can be found easily from Ebay.
Not sure where you are, but I am zip 29607 if you are nearby and would like to hear and open 1 up.
