Depends on what ear/headphones you are using and who you are.
As you should know I pretty much replaced most of components in at least one of my DSD's.
It was a good experiment and a great experience and I can confirm that utilising thin film 0.1% 0805 resistors, PPS SMD caps, sandwiched 0.1/10uF x7r bypass caps, lo-noise LDO's and better inductors and even quality transistors improves things a lot... Funny enough my heavily modded DSD is great, but I prefer very basically modded one for certain 3-4 way BAs.
But replacing components for better quality (I don't really subscribe to this notion of "fake") components can be a can of worms you don't want to open unless you are ready to deal with the consequences ($ and time and a really high chance of destroying your DSD or two in the process).
But this "improves things a lot" should be properly contextualised as a manifestations of a law of diminishing returns: stock DSD is like 80-85, maybe even 90% there sound-wise, but to squeese those extra 10% becomes an expensive and time consuming affair...
Is it worth it? If you are me (fanatical sound purist, DIYing my own IEMs and having acute auditory perception and not willing to enjoy music unless it sounds JUST RIGHT) - definitely YES.
If your game is having great sound on a budget...
Change LDOs, OpAmp and maybe output caps and budget audio nirvana has been attained. The key word is
budget, and it is an audio nirvana... But a budget version of it.
PS: let me know if you need assistance with picking quality components should you choose take a plunge I'm sure
@Merlin-PT will be happy to help too, provided he is back from his travels.
