New First Sound preamp in-bound...
 
Just an update for the gang...

Just got word from Emmanuel Go that my First Sound preamp will ship out next week.

The model is the First Sound Presence Deluxe MkIII-SI, a 2 chassis unit w/ the Paramount Special Edition upgrade using Audio Cap copper capacitors.

The First Sound preamps are essentially "bespoke" preamps, each one crafted and tuned specifically for the owner's system and system components. The design is a true dual-mono design, essentially two preamps in one main control chassis "box" with the PS transformer and PS capacitors housed in an external chassis to maximize performance while minimizing the impact of noise and vibration on the main circuit. Additionally, there are two chassis in in the main control unit, with an inner chassis comprised of copper-plated steel to function as a Faraday cage to further reduce the impact of external noise.

Special care is also provided to provide vibration-damping and even the fasteners were selected based on comprehensive, long-term, listening tests.

Notable are hand-assembled volume controls, utilizing individual exceptionally high-quality metal film resistors at each gain position and a massive power supply, exceeding the power supply capacitance and "stiffness" of many high-end power amplifiers.

Emmanuel is presently "crafting" it to match perfectly with the other components in my specific system. :thumbsup:

I'll post photos of it when it arrives.

Just read up on this. Seems like it will be a great addition to the system.

The only website I see seems rather confusing and shows 2017 Product info. Any links Stephen?

Congratulations Stephen in advance of its arrival! First Sound preamps are hard to find i user systems as they are nowhere near as widely known as they deserve to be. Truly one of the best preamps in the world! True SOTA...

Hey Jim,
No, that's the only website; its a bit out-dated, for sure.

Thanks, Mark, cheers.

So, here's some more info on the First Sound preamp I'm getting:

Basic Model: Presence Deluxe Mk III

Dual Mono Construction using Copper Plated Steel Chassis
• Step Attenuators, Ladder Type using individual resistors (see below), designated as LTH 92
• SPS 2.0 External Power Supply w/ detachable umbilical cord

The First Sound that is on loan from a friend...standard silver face plate and knobs.

MkIII-S upgrade
• MPDA (multi-phase differential array) developed by Shunyata Research. A sophisticated and innovative proprietary power line noise reduction filter array. Uses advanced 30 element surface mount components that significantly reduce power line noise.
• PSDS (power supply delivery system) An advanced system utilized for the power supplies..
• Upgraded main circuit boards
• Upgraded power supply circuits boards
• Additional 500 extra steps in the craftsmanship of this upgrade
MKIII-SI Upgrade
• As above with the addition of proprietary component filters that isolate electrical noise.
Paramount Special Edition upgrade
As the Presence Deluxe MKIII-SI with the addition of:
• LTV 92 Step Attenuators, Ladder Type attenuators using naked Vishay Resistors
• Upgraded (Stage 3) Capacitors using AudioCap copper capacitors
• Expanded power supply capacitors
• Special Edition grounding topology

Thanks, Tony.

The one I have here on a very kind loan is quite amazing...
