buy a cheap DAC like a Dragonfly, and then only buy upgrades that can be returned; use blind listening tests to see if you can tell the difference - if not, back it goes
meanwhile assemble some program material to test - not just your favorites but whatever people claim shows a big difference between DACs (which range up to the $30,000 Nagra)
why the lust for the 851D?
(I am a big fan of Cambridge Audio and have one of their original Dacmagics, but you need to think about the components of gear lust to make the best choice. This also has the salutary effects of 1. slowing down your rush to buy, and 2. satisfying that itchy feeling somewhat.)
