@ghdprentice hit the nail on the head when he said “Then there is a question of does the sound characteristics match your tastes.”
Like him a Benchmark DAC sends me running for the door. A friend of mine who has been in the hobby/industry for decades really likes it.
So there’s the rub, it depends on what you want to hear. Aggressive? Smooth? Hyper detailed? Syrupy (is that a word)? The answer to your question depends on what you’re chasing.
To my ears yes there bad sounding DAC’s.
