Supratek Grange/Cabernet preamp

Supratek has a new addition to their preamplification product line: the Grange/Cabernet (full funtion/linestage). It seems to be a refinement or modification of their former flagship offering (the Cortese, still in production), at least the phono section is. Are there any 'goners out there who can provide some info on this product in terms of its price/performance, particularly in reference to the Cortese/Sauvignon? Any owners of the Syrah or Cortese who may be contemplating an upgrade? Supratek has a new website at www.supratek.biz.
