There are devices available that use very high quality clocks that can be inserted between digital source and DAC to help assure accurate timing and reduce jitter. Such a device with most gear can probably only help and not hurt. How much in each case would likely vary. Some digital source devices may already have extremely accurate clocks and timing and not benefit.
Its hard to know how much difference might be heard, but no harm in trying probably, especially if a satisfaction guarantee is offered by the seller.
Also some DACs are designed to reclock the signal more accurately out of the box, and are hence less likely to benefit from a solution like this. BEnchmark is one DAC brand like this that comes to mind.
Bottom line is more accurate timing of data into the D to A conversion process, however or wherever achieved, should always yield better sound
If doing something like this to help assure low jitter and digital timing quality does not make a difference, then a different DAC with different flavor of sound might be the next thing to try. All DACs should and likely will sound diffferent, so individual situations and preferences may be the main factor here.
It would be nice if these kind of jitter reduction devices provided some kind of reliable metric display to indicate how much difference in timing quality is actually measured case by case, but I do not know of anything that does this, so you kind of have to trust the theory and test it with your ears as best you can.
In practice, most decent quality digital sources made in the last ten years or so that I have tried all sound similarly quite good to me when used with the right sounding DAC. But I suppose there is always a way to do better. But it can be splitting hairs sometimes I fear and hard to determine for sure.
Another thing to try that can make a difference is changing the length of the digital cable to avoid reflections and such and enable more accurate signal transmission. Longer runs of digital wire are rumoured to sometimes be superior in th is way to shorter ones. Another easy thing to try if you buy used especially and do not overpay or buy from a wire company also with satisfaction guarantee of some sort..
