You are correct. I think he mentioned it in one of the Nelson Pass Interview videos presented by Steve Guttenburg aka The Audiopheliac.
Ive heard or built most of these and Nelson’s descriptions seem similar to my observations. Also worth note, I could easily and happily live with any of them as my only amplifier.
Somebody asked about the Burning Amp series and I’d describe the BA-3 as the perfect combination of F5 and F4 (because that is almost exactly what it is...) essentially everything good about both with no downside.
When asked point blank for a suggestion on what to build first, I suggest Aleph J, and I still stand by that, I love it, it’s a great amp, and nobody who’s built one that I know of has disliked it - it’s an exceedingly pretty amp and if you’ve never heard real class-A, you will be completely flabbergasted.
For what it’s worth, (and to further confuse those not sure what to build) I’ve had M2x in my system since it’s been built, and if you forced me to choose just one, BA-3.
All that said, when comparing these amplifiers you must envision yourself standing in a garage entirely full of Ferraris, and asking the question, “which of these is the most Italian sports car?”
Awesome, thank you sir! That is also very helpful. Along with the F4 discussion, and of course Papa's input, this has become a very useful thread for someone new to the Pass DIY amps. I think it would make a great addition to the Pass Labs Stickies, or at least the "Favorite Threads and Posts in 'Pass Labs'"thread.

No love for the F2/F2J?
I just finished my pair of F2J mono blocks and am absolutely smitten with them. They are a match made in heaven for my DIY Oris 200/Lowther DX3 front horns.
We are still honeymooning, but each day I am enchanted further by this combination.
There is such a low noise floor it is spooky how music materializes.

F7 is an F5 with lateral mosfets. Like a polite version of F5 except for
the high damping factor, an excellent little trick.
It’s funny you should say that.
My long time affair with Front horns and different fullrangers is still running strong. However, lately I have developed a new obsession to try put together a Sato type horn based on a pair of Dukane 5A540 or multi-entry horn based on some Radian neo760pb and B&C 8pe21.
I kind of love the idea of keeping a single point source as much as possible.
Thank you for the feedback and this wonderful amp design!
