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.

What’s your budget, what do you like about your current speakers, and what aspects are you looking to improve upon?
My budget is 1800, but i could be flexible. I like clarity and good bass.
My current speakers lack a bit of strength already and tweeters are damaged so that is not helping on the clarity side. My current setup is a bit unbalance since my rear speakers are CM5s and the center is a Cm Center but front are not that bigger and have been damaged a  bit over the years.
You don’t mention a sub.  If you don’t have one I’d get something like the CM5 monitors (or whichever monitors best match your center, which is key) and use the rest of your budget to buy something like an SVS PB2000 sub.  Adding a good sub will bring you far more HT enjoyment than floorstanding front speakers, and the monitors will work just fine in that role.  Hope this helps, and best of luck. 
For floor standers the Vandy 1's, especially coupled with subs is a good move.
Though I would suggest looking at the VLR's, as well. They are bookshelf speakers but, like the 1's, when coupled with subs, are an unbelievable speaker. I heard them with a Belles Aria integrated/ Aurender N100 and was blown away. When a set of AQ William Tell speaker cables (not cheap) were added (without subs, mind you), I was floored.
Just PM agon member ctsooner. What we both heard could make the angels weep. No exaggeration.

I prefer the 802's over the other options.  I have owned the 600 series and the CM10's.  At the end of the day your ears will have to guide you.

I have a pair of full size floorstander Martin Logan Motion XT60’s , very good finish and plenty of bass if you choose.  I like them because the midrange/treble response is excellent with a 6.5 “ midrange driver and ML’s excellent version of the HIEL folded accordian style tweeter . Very detailed and able to decipher higher volumes without becoming harsh . I have my Yamaha S-2100 hi end integrated amp treble set at neutral, the midrange /treble response is that good . A slight boost in my bass control , sometimes back to neutral. The XT-60’s are impressive, both in sound and finish. They make smaller floorstanders plus stand mounted monitors in ML’s Motion series .

@victorjs  -  Considering your primary use is for HT movie watching, I would stick with the old advice that says you should have all speakers voiced the same. To me, that would mean stick with the CM series, as your rear speakers and center channel are from that series. Getting your 5 speakers (Fronts, rears/surrounds and center) to be voiced the same would be a good goal. Are your center and surround S2 models in the CM series?

If your primary goal was 2-channel audio, I might offer different advice. But considering you are primarily HT, keeping all speakers voice the same should be a focus.
I will agree with reubent, probably better to stick with your CM series since you seem to be a home theater aficionado. My Martin Logan recommendation was coming too much from the 2 channel music side , my home turf . 
@thanks everybody this is getting very interesting. @reubent I see your point that that was my thinking at the beginning. But i have another option. I have a second pair of CM5 in my studio just for music. I could put those in the HT setup and get some good towers for music.

@bobedwards thanks! I only need a pair of towers, so my full budget could be allocated there. 

I also can get used speakers, since the good ones age quite well. I have a few others on my watch list plus the ones you guys shared.
- CM9 S2
- Kef R5
- Kef q50
- SVS Ultra
- Martin Logan Motion XT60
- Klipsch R8000F
- DynAudio Excite 

In summary, I want to get the best pair of towers i could for the money, I have good amplification I just don't want to over do it. The BW Matrix need the High Pass Amp thing, so not now I guess , maybe in he future.
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 ?
I have the 802 S2s with upgraded crossovers and the BAF.Best speakers I ever had. They look like Darth Vader's kids, but worth it.
Absolutely de 802. 
But what is really lacking to your system is the brain. You will need a pre amp and an amp.
the marrantz won’t push the 800
that was my mistake when started

i am using now 
803’s with nad. 17 feeding a classe amp5

started with the 803’s pushed by a big Yamaha 
my problem only solved when I upgraded my brain 
I’ve heard over 60 pairs of speakers myself in the past 3 months 
do not listen to anyone who has an opinion that hasn’t heard what they’re recommending or can’t articulate what they like so you can determine if your tastes in audio are compatible 
the biggest issue for me is brightness - finding a speaker with clarity was easy, but finding one that I could listen to for more than 20 minutes without fatigue was another story. For your budget no question is the monitor audio silver 300 (current version) - no fatigue and had the best overall presentation beating out stuff costing up to double its price 
You might also look into the Tekton Line.
Plenty of options in your budget range.
If you are planning to keep your cm series center and rears, the Cm 10 is your best option. Since all the speakers will have the same tweeter and crossover design, they will blend perfectly for the best music and home theater experience. Anything else will cause a mismatch and further aggravation.

Consider building a well engineered kit. The SEAS Thor kit, which sells at about $1800 for the drivers, is very similar to the Joseph Audio PERSPECTIVE2 Graphene, which sells for $13,000.

That $1800 only gets you the drivers and crossover.  You'll spend another $300 to $500 on materials and such. The hardest part of building any loudspeaker is making it look good. Veneer work takes some doing. On my first projects, I finished them in Formica, which comes in thousands of finishes.

Some like to paint their enclosures and that's a reasonable option. One guy I know took his enclosures to an auto body paint shop and got an incredible finish, but that costs a bit.
