High Output Preamp for First Watt SIT-3?


I'm new to the audiophile world and recently purchased a First Watt SIT-3 with Magnepan .7s.  I have a Mytek Brooklyn Bridge for streaming, though I prefer to play vinyl with my Mofi Ultradeck.  The Mytek serves as the phono stage (69dB gain for MM?), and I don't use a preamp;  the Brooklyn is connected directly to the First Watt. 

I understand that the SIT-3 is only 11.5 dB of gain, and that's extremely low compared to most amps.  I like most everything about the system except for the fact that I have the Mytek maxed out volume-wise many days.  Certain LPs are cut quieter, and I wish I had more power.  There are times streaming where the Maggies aren't getting to their sweet spot.  I realize the Maggies are a lower sensitivity speaker. 

What should I look for in a preamp to fully drive the SIT-3?  Eventually, I'd like to replace the phono stage instead of relying on the Brooklyn.  Is there a tube preamp featuring a phono stage with sufficient output to drive my amp in the $4k range?  Otherwise, I'm eyeing the Modwright PH 9.0 and a linestage preamp, realizing that this will probably be costlier.  I'm looking for a warm sound, not analytical but engaging. 

Any help is greatly appreciated.  I'm a working musician with a basic understanding of related electronics but little experience in this world.

Thanks atmosphere,

The replies  from Al and joeinid (per Nelson Pass comments) were  clarifying explanations.

I don't know if this is in any way helpful.  I built the DIY version of the First Watt M2X.  I used my Cary SLP-98P preamp with it.  Lots of gain with front-panel level adjusters for each channel.  It sounded great.
There is an incredible level of "shoot from the hip" commentary about the SIT-3 and the Maggie 0.7 pairing. Yes - Maggies are notorious for being a tough load. But - as Vladimir Lamm put it to me a long time ago, "it's not about the watts , it's about the current". For those of you interested, I connected my SIT-3 to a pair of 20.7's I own and while they didn't blow the doors down, they ran the Maggies to satisfying levels. Earlier comments are spot on - Herb Reichert (whom I respect as a straight shooting reviewer), did in fact say the 0.7/SIT-3 combination was fantastic. So did Steve Guttenberg. So, armchairs reviewers can take a back seat to those of us who have actually experienced the combination. Several posters here have heard the combination or own it - listen to them. Forget the rest.
I have owned 3 open baffle speakers I love/d 2 of them. Which one didn't I? Magnepan 3.5Rs. I tried so many things, biamping, then active XO. After 2 frustrating years I replaced them with Emerald Physics KCIIs (open baffle, super efficient and about half the height,

I also have a SIT-3.  I recently sold my Magnepan 3.7i, but I can tell you I was surprised at how good the SIT-3 sounded on them within reasonable volume. I currently have Devore 0/96 (nominal impedance 10 ohms) and the SIT-3 doesn’t seem to be a great match for them. I recently got Tekton Moabs (4 ohms) and the SIT-3 is a very nice match and very musical combination.  The SIT-3 is a wonderful amp with the right speaker
