How much difference does an anti-vibration audio rack make

Hi,

I have just put together a Hi-Fi system. It's a two channel system consisting of B&W 800D3 speakers, McIntosh C1100 C+T Pre-Amp and two McIntosh MC1.25KW mono blocks. I considered buying a carbon fibre anti-vibration audio rack from Bassocontinuo (Aeon 2.0) but did not finally end up buying it due to the fact that there were two many racks in my living room which houses my Hi-Fi system. I am currently using a lovely solid wood TV cabinet to house the above equipment.

Question is whether the system gives me a sub-par performance due to the absence of a specialist audio rack or the difference is immaterial. I could not try it to determine as the carbon fibre racks are not stocked by the dealer due to the costs.

Thanks
