You're right, buzzforb. I'll update the results this evening.
Sorry, but I was commenting on using lateral mosfets to" clean" the F5 sound. I thought clean was one of the major descriptions of the F5.
Perhaps this is due to the hexfet having higher distortion levels than laterals
Just for information, there is an app-note (TI?) showing that Toshiba verticals had even lower distortion than the Hitachi laterals; overal the differences were not so large.

According to post #26 by the master designer, the F5 is a little unforgiving.
Perhaps this is due to the hexfet having higher distortion levels than laterals and new SiC JFETs.
Actually, if you want a more "forgiving" F5, use the IR Hexfets instead of the
Fairchilds. The Fairchilds have lower distortion.
I am waiting for a delivery of LU1014 to finish F3......than I will give my points!
At the moment my favorite in the overall presentation is FFOUR!
I admire the relaxed way he is making music and and giving crazy details at/in unexpected moments.
F5 is impressive by throwing the music in the room with impressive force...... But for longer hearing I prefer FFOUR.

O.k., last days I tried F3 too, I cannot tell you exactly the reasons ........but I still like F4 more. This time I do not find the right words...
Another thing that I can recommend if you own a F4, drive him for a test with one pair of IRFs only......! And go up with the bias to the level of F5.
The sound gets younger....more fluidness, better highs
(less bass), but my open baffles stopp nevertheless at 70HZ and I have still no subwoofer.....
I was inspired to do this by Nelsons M2 also using only one pair of IRF and by Zen MOds crippled F4.
Less sweet than a J2 clone (J2 clone enhances the voices wonderful, but lacks a bit of precision) and more in the direction of F3 and Aleph3.

I'm confused.
Where does the Aleph 4 fit into the range. Is the Aleph 4 the same as the F4 ?
Does someone have the schematics for the F4 and F5.
Where to go with the Aleph 4 if the F* is better, remember that the Aleph 4 uses +/-48V (even though mine is +/-43V) and 6 IRFP244s per leg, 24 in total.
