Peachtree Decco speaker decision help

After a lot of thought I decided to get a Peachtree Audio Decco unit from Peachtree directly for $500. I just ordered it last night so hoping to have it by next week. The system will be used in our family room which opens to the kitchen. 18x18x9 room which opens up to the kitchen. Anyone have thoughts on some bookshelfs for this little Decco? I have read that the unit is best used with speakers in the 87db rating. Looking to spend no more then $400 on speakers. Planning on spending no more the $100 on speaker cable. Some speakers on my short list.

1.) PSB B25
2.) B&W 6 series?
3.) NHT classic 2/3?

Any experiences will be greatly appreciated. Thanks and Happy Thanksgiving.
