Default POLL: Which is your fave Pass design ? F3, F4, F5, AJ

I'll update the results as needed.

Mine is a 2wpc jfet push-pull so it doesn't count.

Chime in !

My vote is for F5.

Point to note: There is an overwhelming majority of people on this forum who have built an F5 over other Pass designs. Therefore I suspect the favorite will be a F5 too.

I really like the F3-circuit! Incredibly nice and elegant, really a modern classic.

It's a pity it's not at all suited for my upcoming speakers, so there's not much reason for me to actually build it.

I'm in the F-5 camp, but its the only Pass power amp I have built. Variations on it, Dual out put Cviller boards and F-5balanced are on the building table, as well as Aleph, both mini and a larger to be determined model. I built the F-5 because of the tremendous popularity of the build, and it seems to have more beans than some of the others, which I need in most of my systems. I like it so much I've got another getting close to done, if I could find a little more time.

I'm currently using an F5 built using cvillers pcb's. Great sounding amp with dynamics and detail. I'm going to have to go back and retry my Aleph 5 but at the moment I'm loath to turn the F5 off. There's a set of PD's AJ boards awaiting assembly so my opinion could change.

A mix and match of the Zen and Fx series amps, to fit your taste and speakers. Perhaps add a bit of Pumpkin to the potion.

Everything is possible....to do the impossible just takes a little while longer.
