X250 Isolation?

Would a Pass Labs X250 benefit from isolation devices or not. As my amp is 110 lbs and is on the bottom shelf of a sand filled rack I'm wondering if isolation devices such as cones or isolation pucks would be a true benefit. I have isolation pucks which I was using under the amp but after experimentation I find the pucks work better for under the isolation rack which my X1 preamp power supply sits on. I could always get brass cones for the preamp power supply and put the isiolation pucks back under the amp but I don't know if it would make much difference due to the weight of the amp. Any thoughts?

Hi Sean,
I used three pucks that use a ball bearing type design made by Orchard Bay a company in Washingington that machines cones and things. I got them from Stewart at " A Sanctuary Of Sound". He is an Audiogon dealer. They are pretty heavy duty ball bearing devices weighing almost 3 lbs each.I wasn't convinced they had a true effect until I removed them for a few days. Upon returning them back under my amp I regained better sound. I had removed all my isolation devices and added them back slowly one at a time over a period of a week to see what each device did. Eveything made a positive difference to one degree or another.

Having been experimenting a bit I have come to realise that my system does sound quite alot better with the isolation puck devices under my X250. I don't know why as the amp is heavy on it's own but with the isolation devices under it the music is more alive.
As for the Sistrum products I hear they are excellent from many and perhaps one day I will try them but for now I'll leave well enough alone.
