Congratulations on your new Beovision 10 purchase !
You mention USD, so I am assuming you are located somewhere in North America, where the unform building construction and electric codes are somewhat different than Europe. As the Beovision 10 is either a floor stand, or side-swing wall mount, I might ask the following:
1. I would first speak with the B&O installer, and have the installer walk you through the entire process: The exact screws and bolts used, mounting the plates, proximity to electrical mains, etc. Ensure a full, step-by-step comfortable understanding of the processed described to you.
2. Wall construction, and at the point your BV-10 will be mounted. Wall construction, and the load bearing capacity there. If US wallboard (Gypsumboard ) is present, do you find a single stud or double-stud mounting point underneath.
3. Solid masonry (as I have in 3 properties unfortunately) is a significantly different mounting procedure. A great deal of work, and dust, but it can be done.
4. In Europe, a common cable and mains method is to sheath all into plastic covers attached to the wall between the BV-10 and the mains electrical socketl, which are then usually painted. North Amerrican UBC compliant electrical cables require approved conduit protection ( aluminum or silicone ) within walls. This application requires some wallboard cutting, reboarding, and painting, but facilitates hiding all cable and wires. If this is a consideration, and one has not done this before, employing a wallboard subcontractor would be helpful.
Personally I enjoy the B&O minimalist "look" of the equipment, and hate any exposed wires or cables. Everything I have is wall mounted, with all lines hidden, a bit of work, but it can be done. Even when your walls are 6.5 inches thick.
5. My mantra to the engineers that work for me is to Think ahead, and out of the box. Seven years ago I posted the suggestion that future BV models should have at least 3 HDMI plugs available, which surprised some on this forum as an extravagance.
Considering now a Beoport, Direct-TV, Apple TV, DVD, PS, ROKU, Wii, WI-FI, and of course HTPC additions, always look at the possibilities of additional electrical service (sockets) and other lines (such as direct Ethernet ) for future applications to your system. Personally, I enjoy SAT TV, but cut SKY etc. over streaming, so one less appliance used x 3.
I am sure you have already considered lighting, glare, sound, seating and other subjective requirements, along with the neighbors.
Programming the BV-10 ? That's the really fun part: Save it for last !
