The biggest, most noticeable improvement? Well, lessee...
First it was the speakers
Then it was the amp
Then it was the cables
Then it was the room
Then it was the treatments
Then it was the cdp
Then it was the DAC
Then it was the preamp
Then it was the amp again
Then it was the speakers again
Then it was the DAC again...
Get the point? The point being that any component or adjustmet to the listening event carries the capacity to be perceptually the most impressive improvement encountered up to that time. I'm not saying they all do all the time; one must select well to get such a gain in a component.
IOW, it is a fruitless endeavor to seek a magical component which supposedly will confer the best gain or improvement. I have heard representatives from all of the above with the capacity to stunn in terms of improvement of a rig's sound.
