Chardonnay is linestage of Chenin (formerly Syrah), Sauvignon is linestage of Cortese, and Cabernet is linestage of Grange.
I am familiar with the Audion but more importantly have not heard it with your gear which is really the key in evaluating any component. That being said I come back to my previous points regarding shorter signal path, etc. and the advantages of them.
How do the Chenin and Cortese compare you asked? I guess my thought here is to contact Mick and get the scoop from him. Initially I was going to buy a Cortese but after numerous emails and discussions with him decided to have a Grange built; it matched up with my other components better than the Cortese. You only live once I suppose but we all live on budgets. One of the features that comes with Mick's preamps is they will sell quickly and without much $$$$$ loss, if any, should you need to move it. I can't recall seeing any Supratek preamp lasting more than a few days on Audiogon. Take your time and make the right decision.
