Bookshelves affixed to a wall or inside a closed back bookcase are usually bad news with most rear ported speakers. The rear port needs room to sound its best and when it doesn't have the room to operate properly, the bass can sound smeared. Sealed box or front ported speakers can be placed closer to a rear wall as there would be no rear port to interfere with.
Most multi zone receivers and amplifiers are physically bigger components for obvious reasons. The smallest that I have seen is the Yamaha 497 which goes for about $400 and measures 12 1/8" deep.
