Preamp Deal of the Century

I have scanned with interest this thread, seeking info about perceived differences between the First Sound family of linestages and the Supratek family.
It seems that a probable majority of posters prefers Supratek devices over the First Sound Presence II. On the other hand, First Sound has a wide range of devices, very much like Supratek, with approx 15 different models. A number of chassis ranging from 2 to 6 per unit. Power supplies ranging from approx 200K MF to over 500K MF. Choice of series step attenuators or ladder step attenuators in the volume controls. Choice of Holco or Vishay resistors in the volume controls. MIT, Cardas or custom copper capacitors. A variety of wiring and grounding designs.
I have not had the fortune yet of listening to either the First Sound directly, or the Supratek family as such I cannot comment on audible differences. yet I seem to have observed that the comparisons this far may have been mostly between various models of Supratek against the lower models of the First Sound lineup only. Has anyone performed some matrix comparisons? Or at least compared the higher end Supratek against the higher end First Sound models in the Paramount, Special Edition and Statement series?

Thank you TVAD, loved your post!
But no, alas I have no bias. Rather I think in matrices. I was just observing and pointing out the slightly skewed distribution of comparisons in this thread and tried, and should say succeeded, to elicit a reaction. I did speak to Emmaneuel just today: unfortunately there is no First Sound in Austin where I live. Next week I'll be travelling to D.C. but there is no FS dealer there either. There is a proud FS owner in Virginia, not far from D.C., but that is outside of the D.C area.
I should really kick myself though. In january I ended up in Florida in the general vicinity of High End Palace and should have visited there, but did not realize Larry Diaz carried First Sound at the time.
I am delighted that you are defending FS!!

Actually, I am also interested in anyone who has heard both First Sound and Supratek units in a reasonably direct comparison.
