Audio as an investment? You have to be kidding. Spotted a Château Palmer 1972, if I remember correctly, the other day and was astounded that the asking price was around $495 a bottle. I bought one around 1982, the time I bought my house, and remember paying something like $50.00 for it. Now that is something that appreciates. Have you ever heard of any piece of audio equipment (except maybe for the very exceptional product like tube tuners) that do anything other than depreciate? Counting yourself lucky because what you bought depreciates less than something else you may have gotten is not a proper yardstick to measure an investment. I suspect you have fallen prey to sellers of high priced goods that like to call an "expense" an "investment", to provide the customer that little extra push to get the person into a comfort zone and to sign on the dotted line. Oh, and as for my investment in the Bordeaux, well my wife and I drank it way before it appreciated in any degree. C'est la vie
