Ha ,I am using Radio Shack speakers and amp from 20 years ago ! Wish I had better ,but don't have much of an income anymore . I like to listen to Steely Dan as a reference but never have any luck reproducing their sound ! It would be neat to be able to master on a professional level , I think you need higher quality stuff than what I own though . Maybe someone will write a mastering for dummies on a budget post (hint to rharv)in tips and tricks !
