I was mostly intrigued by the demo J2 price. Great deal
If you can't build a J2 or borrow one, then buy one.
Like the F4, it's one of those amps you just have to hear if you're a fan.

I built ZM’s babelfish J2 with SS parts. Assuming that’s a close experience to the production J2, I agree with you 100%!
According to Mr Pass, the specs are actually improved for the F8.
It is similar to the J2 amplifier, but has only one front end transistor instead of six, operated as a current feedback amplifier (CFA) as opposed to the J2's voltage feedback (VFA) differential input. This front end is more consistent with the single-ended approach to amplifier design and yields a purer second harmonic character, less distortion with lower negative feedback, greater bandwidth and higher damping factor.

As has been mentioned numerous times, specs are objective while listening enjoyment is subjective. Better specs don't automatically increase subjective listening enjoyment.
I build EVUL's version of J2 and was not expecting what I heard.
If F8 is an upgrade, it must be fabulous.
I agree. The F8 does seem like it may very well be a refined version of J2.
