I have a pair of PSB Image 5t paired with a Mcintosh MA5100 in my office (specifically for music)

In my family room, I have a Harmon Kardon AVR125 receiver and I would like to do 5.1 as well as stereo. I'm looking at PSB again becuase I love the way the Image 5t's sound but it's going to take some time to get the floorstanders as well as the center, surrounds and sub. There is a local seller selling JBL E80 towers with JBL N Center and N24 for the rear speakers for a really low price ($150).  Can anybody give me any info about these speakers and maybe whether or not they will be at least nearly as good as my PSB's? Thank you for your help.
