What can you tell me about First Sound pre-amps?

OK TVAD, I check my Excel chart and I was wrong. There are sadly only 13 (thirteen) First Sound variants.
I constructed the spreadsheet from the 2004 price list with some additional info from the First Sound web page and several reviews. Emmanuel has verified my count.

Oops, forgot again. The new variants are 'Plus' variants on the Paramount theme. Thus:
Presence Deluxe Mk.2 4.0 with Paramount Plus Upgrade.
Paramount Plus.
Presence DeLuxe Statement with Paramount Plus Upgrade

For example, here are some of the key features of the Paramount Plus:

Controls: 2 volume, 2 source selector, 2 tape switch, 2 mute switch, 1 cap discharge switch
Chassis: 3 total (2 power supply, 1 amplification/control)
Custom machined anodized Aluminum (2)
Wiring: Paramount wiring
2 mono power supplies
PS Capacitance per channel: 278,000 mF
Total PS capacitance556,000 mF
Capacitor type: Cardas Golden Ratio Capacitors
Volume control types: Ladder step attenuators
Attenuator capacitors: Vishay S102K
Number of attenuator capacitors: 46 x 2
Power supplies: 2
PS Ombelicals: Detachable
Paramount grounding

Calloway, you suggested earlier you were planning to upgrade from your Presence model to a real Paramount. Have you ordered/received your unit? You may be able to comment on perceivable sonic difference between Holco and Vishay-based models.

No kidding TVAD about the number of variants. Even with the spreadsheet I tend to get confused.
And you are right, it would be interesting to learn about the rest of Mphnkns's system.
