Is there any particular reason you are interested in the Peachtree equipment? A much less expensive A/V receiver will provide plenty of power for your needs. I can't see the value added by the more expensive electronics which will sound the same as any other gear which measures comparably. Plus the A/V receiver will probably include some type of room correction, and bass management, which will be usefull when all of these folks talk you into a sub LOL!
