My Meridian sits on top of my 551 amp which just sits on a small square light oak table from Habitat.

I used to use the following - Taget Steel rack, paving slab, Mission isoplat and Sorbothane feet. I then tried it without all that crap and it still sounded the same. Looks a helluva lot better now too.

Never regretted it! My PC now sits on the Isoplat as the plastic cup feet make it slide easily on carpet. The AudioQuest Sorbos are chucked in a drawer somewhere. The target rack was given away and the slab went in the foundations of my dads shed.
