I don't see a problem with storing audio equipment that long. I must ask, why buy it if your not going to use it? The audio market is very similar to the computer market. Stuff gets outdated quick. Its almost like buying a new computer and not using for 2 years. By then its old and outdated. If it was me in your situation. I would just sell the stuff and then buy new stuff when the time comes. That way you at least be up to date. Not to mention the fact that with a 1-2year time frame before you install it the warranty will be long gone. It would suck to hook up something and it be dead.
