old components for new small system

I have a perfectly good B&K ST-202 power amp and a PAS 3 preamp up in my attic......is it possible to create a good small room CD only system adapting these to new or used monitor speakers, a CDP and possibly a sub or should I just sell these and create a system where the components are matched from the start...maximum for CDP and speakers is no more than $1500. Thanks!
