Yes it is. James Borgiorno(RIP) designed the original Ampzilla and Son of, his company was called GAS. He resurrected them and improved them and put them out under the name Spread Spectrum Tech.  Wyred4Sound builds them now and they are a great value for the money.  
The Ambosia Pre,  the Ampzilla 2000 mono blocks and the Son of Ampzilla 2000 are all JB. 
The Thoebe II pre and the Son of Ampzilla II amp are both designs that are largely Jim's,  but have been tweaked and finished by W4S.  
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.
