Yea, some high priced DACs sound like garbage so a day and night difference. Others I have heard sound just fine. Just spend days comparing bottom tier chip DACs and the differences are as slight as different filters. I have yet to hear one "markedly better" but I'll keep searching. If I had $10K to spend, it would be on speakers. If given another $10K, It would still be on speakers. They matter and the very best of them suck compared to a $100 DAC. I am NOT saying a $4k DAC may not sound better even on $1K speakers, but money spent on the speakers ( or the room) will make a bigger difference.
It really ruffles feathers, but there is a point where there is nothing circuit wise to improve on after a mid-tier level. Mass market entry tier DACs are as good or better than most studio equipment the music was mastered on. Exclusive, aesthetics, price driven placebo, ego... If that is of value, then the market fulfills it.
