I have a problem. I can't seem to stop building audio equipment. It seems the next phase will include Fonken enclosures and either F2 or F4. I have boards for both and was wondering if there is any speicifc experience with MA drivers. I know the Pass/Alpair sound and I love it, so why not try more. Thanks again!
... how to cure?
However limited to speakers till now, amps likely to follow.
FWIW, Mark's drivers will recieve little benefit from the F2's current source nature (although you could adjust that in the build); it comes into its own with lower Q units. The F4 would probably be a better bet providing your preamp has sufficient gain. I like both for different reasons, although neither is without its drawbacks.
Oddly, my favourite of all Nelson's free, single gain-stage designs is the Son of Zen (with or without the V6 modifications). It's got a certain something about it.

Interesting comment about the SOZ. I think i remeber him saying it was this amp that launched his curiosity in to current drive and the whole dampening thing. It definitely fits the simple build criteria. I have A-J's and they sound great, so this is more about learning and seeing how different things sound. What do you mean by your comment about adjusting the F2. I must admit i don't fully understand. Are you talking dampening factor? I'll do some reading. Thanks!
I think scottmoose speaks of a low Qt of speakers, means heavily damped. With F1 and F2 Nelson made it possible to drive for instance Lowthers to have a deeper bass, because the current amp delivers more Watt when the impedance rises.
Disadvantage, less damping of the speaker in the bass region. Maybe you must fill in more wool.
I think scottmoose says your speakers maybe not so suited for current amps.
As far as I understand the matter.....
