I like the earlier analogy. If you put $1600 in new wheels on your car, it does not make its value $1600 higher
This, to a degree. With the internet bringing everything to your backyard, there is a vast quantity of buyers that never were. Someone will look at that car and say, I love those rims and would have put them on it anyway justifying some the $1600 added to the price. They may not recover all of the $1600 but it will add value to the sale for that buyer. Extras to me always entice a better deal, why not buy the studio monitors you wanted from a seller that is getting rid of his monitors with stands and pads for close to the same price you'd pay for the monitors alone. No brainer, really
