I also mark my volume knob in 3 spots with a pencil. It makes setting the volume between the two much easier. Pencil rubs off if you dont like the spot.

I know that... it was a tongue in cheek post
. That is what I meant, similar attenuator designs (Arek's is rather famous) but "besides the gain stages and buffers" was meaning exactly what you said 
.

I'm slow today. Had 42 fluoroscopy guided injection yesterday. Then ate a couple oxy.
First Sound actually started out building passive devices. Somewhere along the line he went active.

I wish he would make a phono pre

Ouch, that doesn't sound good.

It's amazing. 2 friends are paralyzed and other still in a lot of pain from surgery. I get injections of PRP that keep me petty mobile for about 1 to 1.5 years before I need another round. Cost about $3,300 a round. I don't get why people go under the knife.

Hang in there Rex. Sorry to hear about that issue. It does not sound good at all.
Hattor does offer a SS built in active gain stage or a Tube active gain stage as an option. Who knows, maybe some day they will go the same route. I kind of like it as a passive. It just sounds so good, so natural. I do not see any need to get the active gain, but who knows. I can always add it on if I want to.
If I understand it correctly, buffering is also a petty big difference. Without buffering there are two spots where the impedance changes and the volume is not linier. This is as expected. (I do not understand it completely but Arek described it to me. He was talking way above my understanding though.) This is one of the reasons why some people claim that the Wyred 4 Sound STP-SEs (and Stage 2's) are not true passive (I am not sure I concur with that sentiment). Even though they do not ad gain until the volume is extremely loud, they are using buffering.
Anyway, back on subject. The First Sound looks like a beautiful unit. It must sound amazing. I do admit that I like the looks of the black one a bit better.

Just heard from Emmanuel Go at First Sound today; he's completed the updates to the latest Shunyata Research CCI-X noise filter technology for the dual external mono power supplies for my First Sound Presence Deluxe preamp, and is shipping the power supplies back to me today. I should have them back in a week or so, and they'll require about 3-4 days of burn-in and will be good to go. I also had him install ground posts to chassis ground on my power supply chassis, so I can run a Shunyata CGC cable from the power supply chassis' to the GP-NR ground terminals of my Everest power distributor, so I can make use of it's way cool ground-plane noise reduction system. If you have a Shunyata PD, you should be using this system, and if you're not...why not? 
The Shunyata GP-NR system is quite impressive in the benefits it brings.
I'll post an update here once power supplies are here, and they're up to speed, but my understanding is this is a notable upgrade to the First Sound preamp.
