Choosing between floorstanding speakers.


HI, i am new here so first of all thanks for reading. I want to upgrade the front speakers in my home theatre. Currently I have an old pair of B&W 603S2 hooked to a Marantz NR 1606 on Pre - amps with a Crown li800 Amp. I have 3 options.
1) A pair of CM10 S2, they are asking about 2K (which is a bit over my budget but local pick up) 2) A pair or 802 S3, almost the same price 3) A pair of the new 600 Series (603) for almost 300 USD less. 
I love audio, my usage of that set is mainly movies from BluRay 4K and the usual streaming services. I might listen to music every once in a while but is not its main use.

Thanks for your responses.

Unless you buy speakers that are facades old, buying used speakers are the way to go. Really no reason not to buy used if you don’t mind a ding or two.
Not facades but decades old! Very old speakers frequently have failing surrounds.
What is your budget?
Don’t think you can touch used 802s for less than $10k.
OH yes..I found a goood pair of 802 S3 for 1400 $. My question there is, makes sense comparing with new mid range tech?? Should i buy a Variable Bass Alignment Filter for those speakers ?
