I have the same problem and just went from the open architecture to a BIG cabinet. My equipment cabinet covers the whole wall with the exception of enough room to put my speakers. I have baby gates in front of my speakers when the baby is up. My critical listening occurs after the baby is in bed, and then I pull my speakers out to the proper location (cabinet is now the back wall in my measurements). In addition, I have equipped this cabinet with magnetic childproof locks so the baby can't get in any of the equipment. The other similar solution an audiophile friend did was built cabinet fronts / structure and had the equipment on zoethecus stands behind the doors (with magnetic childproof locks). This was expensive, but looks really nice. He also has an IR Repeater for the remote equipment. I also think this improved his sound due to the fact that the equipment is truely removed from the center of the sound stage, the downfall is longer speaker cables. He also has to pull out his speakers for optimal sound. There is no good solution with carpet commandos and AV Equipment.
Where do you put your TV/equipment?
Most armoire & entertainment centers are big, tall, flat-sided things that sit between the main speakers--not good for your image! I want an open-architecture stand, but I have a soon to crawl kiddo who would use it as a jungle gym! So what do I put my TV and gear on/in to keep it out of reach and not destroy the image I work so hard to get?!
