Kenwood KR-9600

Hello audiogon members
not only I’m beyond amateurish when it comes to vintage audio I’m also a fresh new member with a large amount of questions.
i bought a kenwood kr-9600 yesterday and wondering what speakers I should get to match the amp power which is quite high I believe. I have a pair of Sansui SP2000
would that work? If not what should I look for that is not too expensive ($500 max)Thank you for your help
