IsoAcoustic platforms, feet, etc are a nice upgrade in my opinion. Unlike wires and cable where many say they hear no difference [myself included] I find that isolation does work on anything which causes vibration. I draw the line at amps though.
Isolation platforms
Over the summer I purchased a Timbernation 3 shelf 2 in. Tiger maple audio rack along with 3 in. isolation platforms for my ARC Ref 750s. mono amps. My question is do I also need isolation platforms for my ARC Ref 6SE and ARC Ref 9cd ? I was thinking of also getting 3 in.
maple platforms for each of them. Would it be more for looks or would it really be useful for isolation.
