How much does a DAC do the more expensive it is?

@simao first off, absolutely stunning listening room. Secondly, I feel like some of the focus in this thread around DAC cost isn’t really giving you all the tools that will be helpful to you in discerning different qualities of DACs at different price points, and in determining which of those qualities might be important for you. Here is a link to a recent Audiogon thread that I think does a good job describing these characteristics in higher end DACs that could be applied to DACs at pretty much any price point and could be helpful. There are a lot of comments on the thread, and I might suggest only reading those from the OP for efficiency. Good luck.

+1 for @bolong reference to GoldenSound review of the HoloAudio KTE May DAC, but I would also watch part 2 in which the reviewer tries to describe objectively and subjectively how all that technology translates into what he hears.  Spoiler alert, he uses the word “fantastic” a lot, but for me that doesn’t really diminish the value of his earnest attempts to describe what he is hearing from the Holo May.  If this is too rich for your blood, you might look at HoloAudio Spring.  I personally like Chord and Denafrips DACs as somewhat opposite ends of the audio spectrum, at least at lower price  points, with the latter like HoloAudio being a pretty good value proposition.
