Is the unit broken in? Often this is what a new component will sound like before it is fully broken in. Allow at least 200 hours of play before starting to draw conclusions if you have not.
Also try repositioning your speakers. You can often soften the often hard Beryllium tweeters.
Hopefully it is not actually distortion.
Too good...no. That is not how it works. Now you could have upstream components that are harsh and they are being better conveyed. Then it will be a mater of correcting that.
