I have one of these. Has lasted quite a few years, but then I only have a telly, small center speaker and a couple of pieces of equipment on it. No humongous center speaker and never been dragged across the room. True, it is beginning to bow a bit in the middle so will need replacing once my evil plans of a DSP home cinema come to fruition...

Cinema: DSP5000 (18 bit), DSP5000C, DSP33, 568.1, Quad L-Sub
Music: DSP5000 (24 bit), MS200 + Reviver, Roon
