timlub is 100% correct on this.  They are all JB design but have been tweaked at bit since.
I own the second generation Ambrosia preamp. I think it provides a lot of functionality at a relatively low price point. I have both MC and MM phono stages, a large number of unbalanced and balanced inputs and outputs, tone controls, tape loops, and a nifty volume control which can be controlled by a rotary wheel on the remote control. I think I’d have to spend 2-4 times what I spent on the Ambrosia to buy a preamp with all of its features. 
The second edition Ambrosia was reworked to take care of some of the heat issues with the first generation. The second generation does not have a fan and runs cool. It has a low/high gain jumper. If you don’t play loud, and I don’t, the low gain setting will give you an incredibly low noise floor.

I added the Son of Ampzilla II to my main system 7 months ago. I am bi amping my Magnapan speakers ( 1.7i and Base Panel) with their own power via two amps. My other amp is an integrated amp - a Krell KAV 400xi. I feed the signal from the Krell pre amp out to the Son of Ampzilla. The sound out of the Son of Ampzilla now feeds the 1.7is. It beats the Krell’s amp stage on headroom, soundstage and midrange. Granted my Krell is 14 years old - but it has been a workhorse. I recommend Spread Spectrum Tech.
Huh? What’s it got to do with spread spectrum? Absolutely nothin’!
