Pass Labs 1st Watt Rundown

I have become intrigued with the 1st Watt series and I am trying to wrap my head around the series and the differences within the series, but the internet discussions seem shallow.

Can anyone give me a rundown of the different models, versions, whatever?

What are the differences from one to another?

Did the newer iterations correct problems of the previous models and what were they, or did they simply address differences in power?

Stereo? Monoblocks?

What pre's and the sensitivity of the speakers you used with them.

Anything else you can think of as to characteristics of the different models.

Thanks

It's not the direct answer you're looking for, but on the first watt home page, they list all the reviews. I found 6moons reviews go into quite a bit of depth on each model. That gives you a feel for the different sound characteristics, as well as acknowledging the limited repair parts (held at First Watt for future service) for the SIT3 models.

A random gotcha is that the F7 has a very low amp impedance, so many tube preamps aren't a good match. 

I was in the same boat as your recently, and just went thru many reviews one leisurely afternoon.
