Mapleshade has some excellent ADJUSTABLE rack systems for sale, but
they cost a lot of money- especially if you get a number of shelves or two racks side by side. Of course a skilled wood worker with a good set of plans could build the same thing. I don't like the high prices that come with audiophile rack systems, and it depends on your room and your floor what
you might actually need to isolate certain components. I got lucky years ago and got Deluxe Justaracks (Michael Greene) through audio advisor. The shelves are 2 inches thick and infinitely adjustable. It is a dog to look at but extremely solid, like Salamander racks only on steroids. BUT those threaded uprights
are indispensable IMHO as your system keeps changing over the years.
