Thanks for the feedback - I'm sure that the Graham will be the right step, so that'll be next, together with the ISOL-8 regenerator. I'll report when it's in and set up.
In the meantime - if anyone has run / is running a SSM with Phantom & Orpheus set-up, then I'd love to hear an opinion.
Lastly, has anyone tried a set of Finite Elemente Cerabases under an SSM?
By the way - the PH7 and VM220s all have EAT valves fitted - they don't make them for the Ref 3 at the moment. These added weight, body, dynamics, extension and clarity and were a good, if expensive, move for me.
