Tube Preamp Isolation

I have Aurios Pro under my ARC Ref 3 as well as all my other components including my Lamm ML 2.1's. I wouldn't have it any other way.

Go to an HVAC supplier and buy the rubber/cork/rubber blocks that are used under AC compressors. These are the same as the Mapleshade Isoblocks, but will cost you a lot less.

I use Black Diamond Racing Mk 4 cones under my VTL TL5.5 with good results. It has better imaging and tightened up the bass a little. The Mk 3 cones were a little too bright for my taste.

My experience has been a tube pre-amp is least effected by footer/isolation than any other component including my SS amp. I know that makes no sense, but it is my experience. Having said that I use Aurios Pro, Neuance shelves, bubble wrap, Apollo rack, sandstone base sitting on Aurios pro's. See my vibration philosophy under "system."

I totally disagree.

Have you ever had a look at the damping rings that are put on tubes because they resonate?
