I know that, I'm kind of confused. I have read articles that mention that 5 dollar dacs sound as good as 1000 dollar dacs. My "system" referred to my headphones and desktop speakers that have 3.5 mm cable.
Now you're getting into the territory of pirates and parrots. Be careful what you read and take everything with a very large pinch of salt, There's more to it than 1's and 0s and the chips.
I can assure you £$20-30 quid dac is not going to sound the same as 1k one and the differences is not the chips (mostly). In this world, you do generally get what you pay for.
My best advice is to forget the chip inside it really doesn't matter especially at this price point.
If a $35 dac is all you can afford then there your only options and sweating the "what if's" is completely irrelevant.
But if that budget has been self-imposed by someone's ramblings online then i think those ramblings and that forum is pretty toxic and i'd stay well away from it.
There some great little DAC's on the second-hand market like the Cyrus sound key that i found 30 quid here at the moment.
But if that, what sounds like a self-imposed budget from toxic forum, can rise to around 100-300 (not saying you have to spend that) this will open a whole world of options for you from the audio drogonflys to very very impressive and flexable and chord mojo. (Heaphone amp and preamp all rolled into one) and everything in between.
