Thanks guys for your advise.The rogue setup is closer to $ 4,000 with the 100 watt Atlas and the Rp1 .It just has more imputs ,better phono stage and obviously the pre amp has its own power supply,As the Cronus has to share its power supply with the built in pre amp.I could get the rogue m-180 mono blocks 180 wpc with Rp1 for less than 7,000 but was hoping to keep the cost below that for powering the speakers.

That is why I was suggesting finding out how much power you need using a relatively cheap amp with decent resale market value... The Crown XTI amp idea accompanied with an SPL meter with fast peak hold response will tell you what your power requirement actually is. 1kw into 4 ohms for well under $1k.
Maybe I am going at this the wrong way? should i be looking at the 3.7 for this room? Would the Atlas and rp1 still work or would I need more power?
3.7s will need an arc welder for an amp. Few people would be happy with a lower power amp, 3.7s and a large room.
This is a question of your listening habits and the size and particulars of your room.
The room is not too large for a 1.7 but it might be a bit bass light and need subs. It is a perfect size for a 3.7 or a 20.7 - again depends on your listening preferences.
Whichever speaker model you end up with you need to find out how you listen to it. Which is why I still harp on the amp. It would be a waste if you end up buying an Atlas on Saturday and find out the sound is lovely but too anemic for your tastes in that room. On the other hand if you got a rogue M180 and found it to be more powerful than you need, then you chucked out $3k extra for something you don't need. Last, perhaps you are a secret bass blaster at heart and need a kilowatter to scratch your itch.
The highest satisfaction is expressed by folks driving their 1.7 and more so a 3.7 by something like a Sunfire 600, a Sanders Magtech amp, gigantic tube amps like the old Rogue Apollo and Bryston 7B. On the cheap end, D Sonic and pro audio amps like the XLS 2500 and for a bit more the XTI 2002, on the other hand some will power them with 20 W triodes and be happy with the quiet listening they get.
Agree; that room begs for raw, light dimming power. Another reason I'd personally opt for a 20.1 since they can be bi-amped. My Quick Q4s put out 120 watts into four ohms -which would be fine at moderate levels late at night; but daytime, night club level listening levels the bottom end would gobble most of the juice. And I'm not just talking about popular or dance music either, the acoustic bass solo on Brubeck's 'Trio Brubeck' is a thing of marvel and will drain the power reserves on even the mightiest tube amps. Fortunately I have high current 1K watt mono Emotivas on the bottom to stoke the coals.Now having said that I wouldn't just limit my choices to Magnepans (as spectacular as they are), I'd also consider the big cat Martin Logans, or Soundlabs. And for the same price as a new 20.7 you can get a essentially 'new' Duetta (with warranty), others to consider- Analysis audio, and Sanders.

I know a few of you have mentioned the Martin Logan's .I guess this is what you call a Hybrid with powered sub below.,will these produce the same quality sound as the Maggie's? I assume these would be easier to drive beings they have a powered sub on the bottom? I watched a YouTube video with the Martin Logan's Montis El with the Prima Luna HP man does that sound good ! Well it's YouTube so maybe sound is deceiving. Is the Prima Luna good stuff.Here is the link http://youtu.be/s-rtyg1qvb0
the prima luna design and build are top notch and the reputation is stellar. The price tag not that bad considering what you are getting.
The hybrid idea is great, but difficult to execute. I have my personal nits to pick with the ML hybrids, but I would not hesitate to recommend them for someone who wants stat clarity without losing out on a decently well integrated dynamic bass. They are a greater value with the powered woofer sections.
I prefer the old idea of a CLS with bass woofer towers or Tympani bass panels or H frame open baffle, because it is a tall planar speaker and has less floor interactions than the raised and slanted ESL panels on the ML hybrids. Besides which you don't want the bass to be shaking your mids and treble sections. thus the separate ESL and dynamic bass can provide better imaging than the hybrids.
Satie has it right. There is no way for me to recommend low power amps with Maggies unless you tell me you listen to chamber music at low volumes. Maggies offer a lot of value for the money but the money you save goes back into big amplifiers. My brother smoked a pair of the giant Parasound JC1s and a Maggie 3.6s. The 3.7 can just laugh at 180WPC if you ask them for too much. If you really want to run tube gear, you might want to look at a different loudspeaker or get some bucks together for a real house warming amp. They make stuff like this for a reason:
Arc Welder. :0) The next option I was thinking of was the rogue m-180 mono blocks if the the atlas wouldn't cut it.
