All, I'm getting ready to set up a new 5.1 HT system and would appreciate your comments/recommendations.  Unfortunently, while the boss doesn't seem to have a problem with buying almost 2 grand worth of speakers (didn't tell her I also needed a new A/V Receiver...) she does have a problem with rearranging our family room and I'm not allowed in the living room so this is it.  Although I do listen to music, I'm mostly concerned with HT performance and the setup I'm looking at is this:

As you can see, I'm going to have an acoustic "issue" with the right side of the room which extends out a total of 35 feet through the kitchen.  Obviously, the best solution would be to rotate the arrangement to make the left wall the "front" with the kitchen in the far back.  That would almost be a perfect accoustic arrangement but that puts the TV in front of a large picture window.  I was all for bricking over the glass but SWMBO disagrees so alas, it will not be.

As there is no decent location for the surrounds to be placed adjacent to the prime seating area (wife vetoed stands) I'm planning on going with the 534-SS speakers on the back wall elevated about 2-3 feet above the sofa.  Also, to minimize "clutter" I'm planning on using the 533-PT's in front to eliminate the separate sub. 

My questions are these:  First, is there any chance at all I'll be able to develop a decent listening environment given the huge sound-sink on the right side?  In other words, is it worth investing this much given the architectural constraints?  Second, are the 534's the best choice for surrounds in this setup?  I'm making a lot of assumptions but would guess that the more diffuse nature of the 534's would be the best option on the back wall and I don't see a decent option for side mounting.  Third, are the 533-PT's a good choice for this size of room?  For a similar price I could go with the 533-T with an S-10 in the front left corner.  The 533-PT's certainly limit my options for ideally locating the subs but I don't know how much of a trade-off this will be.  BTW, the Aperion system wizard recommended the 533-PT's AND an S-12 which seems like a bit of overkill.  My last question is regarding the A/V receiver.  Onkyo is just releasing it's new line of AVR's which make a very big step forward in HDMI technology.  There are three potential candidates in this group, the TX-SR705, 805 and 875.  The 805 and 875 are rated at 130 and 140W/channel so I'm positive power would not be an issue with them; however, the 705 is only 100W/channel.  Given the ratings on the Aperion speakers, I'd think the 100W/channel would be sufficient, any thoughts?

 Thanks
