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.

Mini A

Aleph J and F5 on the workbench

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.

Aleph F4 on workbench, Chose this one for increased output.

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.
