Jadis Preamps: has anyone had any mods?

Hi,
Not exactly this model, but a few local Jadis owners have upgraded their units with V-Caps and swear it was much improved - more detail and articulation, keeping the Jadis flavour.

I also had v-caps installed and had the same improvements.
Had the work done by RHB Sound Dezign. They also installed their new dynamic linearty circit. As well as a power supply mod and I am amazed at the results. It's taken my entry level Jadis to a reference level.
