As a Sasha owner who runs Lamm M1.2s, I'm very comfortable with the bottom end. Transparent Reference cable also makes a solid contribution to the bottom end, too.
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!
Thank you for the reply. I need to start looking into isolation. Have you considered Stillpoints? I like how they supposedly isolate vibration from the component as well as the external forces.
And yes, I absolutely loved the Ayre. That remains my reference amplifier. I really like the approach that Ayre takes with their designs. If they made an M series integrated I would have purchased that instead of my current Accustic Arts Power 1. The sound is so liquid and the clarity is exceptional. I think the liquidity and ease of sound is a good match for the dynamics of the Wilsons, not to mention it has enough power to easily control the speakers.
