Just noticed that you already floated a prior near identical ballon first re: bookshelves instead of floor-standers .Yep, a post that generated 3 plus pages without the OP committing to anything.
So my advice to him in this thread, will be exactly the same as I gave him in his last...
Understand your amps capabilities and how they relate to the two key specs of a speaker - impedance and sensitivity. Then make up a short list of models that are within your budget and go out and audition them.
For those of you who will give him recommendations anyway, his amp is a vintage NAD 3020.
