Good for music I wouldn't really know. They are both speakers made to handle anything you feed.
Depending on your genre, if you like boom boom music then the S350DB would benefit more in your other question you asked there.
S2000PRO wins my classic S530D easily especially in clarity.
Bigger range and better attacks in speed.

The S530D is the most calm and slow paced when compared to S2000PRO and S350DB as they are both energetic and hard hitting.
And honestly I like my S530D for music more than other speakers because I am accustomed to the signature of it.

Generally for fresh listeners the S2000PRO will win in music no questions asked.
But the price range opens to many other options like passive bookshelves or good active ones like
-Audioengine A2+ or A5+ if you spend more
-Micca RB42 with Lepai's LP1601S (or any better amps)
-Elac Debut 2.0 B6.2 paired with Lepai's LP1601S (or any better amps)
-Kanto YU4 or YU6 black if there's a seller willing to import

Or maybe bring your budget and hit up amcorp mall to experience some next level music.
