So many choices, but I can only describe my decisions. I have cheap ( a Topping and an iFi), modest (an Okto), and moderately expensive (Gold Note). I did a dac shootout with a friend in his highly resolving system of my Okto, his Mytek Brooklyn, my Goldnote DS10, and his dcs Bartok, To my ears, I ranked the DS10 best, followed by the dcs (which was over $10k), then the Okto, then the Mytek. My friend preferred his dcs over the DS10.
The DS10 is about $5k if you also get the optional power supply. I bought the dac first for about $3.5k, and subsequently added the power supply. It definitely made a difference - I had previously done a two way shootout with same friend betw the dcs and ds10, and I preferred the dcs that time. Do the power supply made a material difference.
