Need help for my HT,looking to upgrade my speakers


Hi folks,
I enjoy HT 70/30%, just bought a b&w HTM2 for my center, looking for surround suggestions as well.
Now using b&w 602's for left/right (would like to change those) , subwoofer is Paradigm seismic 110 (new sub), love the sub would like to keep.
Should I stay with b&w speakers or is there an alternative speaker that would work well with the htm2, I was thinking of the Paradigm studio monitors v5 but not sure how the whole thing fits. For now I'm using a Marantz AVR. Family room is approx 15x20 high ceilings.
Any input is appreciated
Thank you

Hi Tls49,
First let me thank you for your informative thread.
From what I understand I should be looking for a different AVR if I decide to go with the 805's or better.
I enjoy my HT & music played in my family room mostly at (-15 db) with my current avr.
Now that you have clarified some of my questions, I need to decide wich way to go, I'm on my way to listen to the 686 and CM1's
Thanks again
Tls49, I pretty much concur with everything in your post. I do believe the current CM1 is a different animal than the older model, with more recent trickle down from the 800 series. I really like the CM1, 5 and 7. I have not had a serious listen to the CM9 yet, but people I trust like it very much. I. Like the 685 too.

Tesseract86, you are most welcome.

Knownothing, I now remember the original CM1 did not have the Nautilus tweeter tube that is used in the new one, and there may be other differences.

The 600 series is great sound for the money. The CM series is better, however some of the higher price is paying for real wood veneer on the cabinet.
