Tboooe,
Have you look into Minus K platform? I had demo Stillpoint Ultra Mini. There was a very small improvement comparing to my UK made isolation feet. Maybe it was due to the component is aleady seating on the SRA.
I've supposed to address both vertical and horizotal vibration through the use of Solid Tech Spring isolation under SRA then this UK made ball type isolation ontop of the SRA!
I'm very tempting to upgrade my Mc501 to Ayre MXR or Lamm 1.2. However, i'm not sure if either of these amps can control the bottom end of my Sasha. Used Krell Evo600e and used Levinson 53 are also on the list.
No plan to upgrade the Allnic L5000DHT or the K01!
