ever heard these two in direct comparison , both in class A ?
No, I never have, that's why I'd be interested to know your opinion - if you have heard them ?
Sure, but you will probably want something like the LSK-pre http://www.diyaudio.com/forums/group-buys/248957-jumas-lsk-preamp-smd-version.html or Curly-F4 http://www.diyaudio.com/forums/pass-labs/250205-curly-f4.html as a voltage gain stage.
Would mini F4 with sk2013/313 make sense as headphone amp?

Zen Mod,
Simlics bypassed useing Wima MKC.
Changed the sound of the F4 into something very listenable.
Only question now is how they suit the F6.
The F4 soundstage is quite a bit more larger and enwrapping than the F6, which stays more between the speakers - so I'm wondering if the Simlic's and Wima's are responsable for that... I guess I'll just have to try and see...

F6 to drive F4
I was just re-reading Nelson's F4 manual specifically with regard to "flea amps" used with F4
My question - Could I use my balanced F6 to drive a balanced crippled F4?
Basically I want to do the experiment to see if this puts more kick in the bass.
Thanks
Bob

Hey dudes. long thread but I made it through. I have a query;
I have a mid horn, 103dB and treble 110dB. I will be listening from less than 3m. Processing done by a MiniDSP with 2v SE, 4v SE or 8v BAL.
I've concluded that 8v will give me a satisfactory SPL when 'cranking' the DSP to 0dBFS, and I want to optimise my gain structure for the sake of the noise floor.
Here's the q: Of all these frontend options, which would accept the ~12v p-p of my 8vRMS BAL input? And then, to further complicate things, which might also allow me 7dB of gain for the less sensitive mids? I don't require both horns to have the same amps, and in fact I look forward to playing around with the freedom of very low power needs.
I have been thinking of the BA-1, with reduced gain, but have no knowledge of whether it could handle such a large input. Maybe just an opamp BAL-SE into the crippled F4? I understand how to run a stereo F4 balanced, but I'm not convinced of it's CMRR compared to a balanced buffer/gain stage, and with 110dB/w/m in the near field I'm concerned @_@
Thoughts?

ZM's Pumpkin or BA3B.
is for sissies
Are you looking for a fight bubba? I am just a couple of hours away from finishing mine!
Both can operate at only 6 or 0 dB gain? Just read the BA3B thread. Looks good. Any comment on the BA-1 FE at unity gain?
I investigated the pumpkin years back.
at 0db , look for buffer , not gain stage strangled with overall NFB

sissie !
...... Could, say, an Aleph J handle it? ......
J will go berserk with 8V ( any kind) on input
