In terms of measurable distortion? Nothing.
And its been that way for decades. After some 30 years of using various CD players my two personal favourites were also the least expensive. Not necessarily because of their sound more likely because of my low expectations. I really wanted my far more expensive UK race tuned Sony models to sound better, but they didn't. Even the filters made bugger all real difference.
What you might get instead for paying more are features such as Bluetooth, switchable filters, looks and build quality.
Album art display is pretty cool too.
