Thank you jostenmeat!

I had never heard of Sierra 1's but i read some great reviews and i think they are a winning speaker.
My only concern is the fact that i am looking to upgrade the system to a surround sound 5.1 in the future and i don't know how the
tonality will match with other brands(in case i decide to go that direction) and i don't know how good the sierras will be for the surround sound kind of set up.
Any thoughts on that?
You'll definitely want to "match" with the center. The ideal match, believe it or not, is well, the identical speaker, upright/same-plane/equidistant. They make a horizontal, with the tweeter rotated 90 deg. Also, think about it, all of the speakers you see use vertically arrayed drivers. This is because it's the best design for horiz dispersion. Horiz arrayed drivers, well particularly the horiz MTM, suffers in this regard. The reason you see it EVERYWHERE, is because people don't know better, and it came about as a purely aesthetical compromise. That's just some speaker edumaction for ya. (better horiz designs would include coincidental as made by KEF, or WTMW like the high end BWs, which of course are $$$$).
Less that, from the same brand at least.
It's the same thing for surrounds, however, here it's not nearly as imperative. It's still better, distinguishably, IMO when it's the same speaker, or at least from the same lineup. Again, less that, same brand. If you can. If you can't oh well. Won't bother you nearly as much with HT as with mch music. But, even just for HT, my opinion stands. JMO.
Ah and one thing i forgot to mention. I heard B&W CM series and i absolutely loved the details the warmth of the sound. I heard them in an audio store side by side with Paradigm Monitor series ( which i had extremely high regards for) and i truly fell in love with the sound of CMs. I can not afford them because of that extra $500 but that would have been a clear choice.
If you love the CM, save up for em. Bookmark Audiogon. Wait for them to pop up on classifieds, hopefully from a seller with good feedback. Even luckier would be if they were a neighbor, for local pickup. See when this lineup ever gets superceded, then hit up the dealers and offer to take the demos off their hands. Etcetera.
If you like Paradigms, the Studios are a step up from the Monitors. And the Signature is a step up from the Studios.
Ok, I see on Audiogon that the Signature S1 V2s have sold twice recently, once at $950, and another at $975. (and that's as listed, who knows what happened with negotiation). Here is the S2 V1 asking at $1,050. (I think they're on V3 already though? Sorry, I'm not too familiar with the Paradigm family).
