Isolation device under Ayre CX-7e?

Hi,
I was wondering if anyone places the isolation device such as Vibrapod or maple wood board under Ayre CX-7e? What's your opinion?

I put my CX-7e on top of a maple wood board and then on top of 4 Vibrapod last night. THe soundstage was bigger, but the high is kind of echoeing. When i took them out, then the sound is clearer but soundstage was smaller. I just want to get some opinions or suggestions from experts here.

Thanks for reading.
