Yes, have up to four separate supplies in a milled box weighing in at 35 pounds and it is very sensitive to what it is sited on....Control unit weighs in about the same and it is very sensitive as well....Power supply likes short aluminum cones and control section likes large 3M feet.....
isolation of seperate preamp power supplies?
Does anyone have the same type of response that I am getting with my Pass X1 power supply? I notice that the sound I get from isolating the seperate power supply has a huge impact on the sound. I have the hybrid version of the X1 so the external power supply is a little black box that doesn't weigh very much but the differences in sound I get by different types of placement and isolation are dramatic. Today I decided to try isolating the supply with an isolation platform on top of 1/3" of marble slab on top of 1 and 1/2" brass cones that go into my carpet. The sound is quite nice.I am also using BDR cones between the power suopply and the isolation platform. I thought this was overkill which is why I didn't try it sooner. Previously I had my power supply on BDR cones#4 on top of a 2" piece of MDF on top of the brass cones and I thought this was more than sufficient but when I decided to experiment with my extra isolation platform(Skylan)I was pleasently surprised. Has anyone noticed that the isolation of pre outboard power supplies makes that much difference?
