Sure, why not. They'll give you a little 2nd harmonic in the bargain.

Does that mean the design with FQA devices has less, or no 2nd harmonic at all?
Please do tell all...or even a shred... 😀

depends of circ

generally - yes - less

Hmm.....ok.

1 - What's circ?

2 - If the FQA device has "generally less" 2nd harmonic, isn't the 2nd harmonic a typically "desired" artifact for a softer sound? Does that mean, in your opinion, the 240/9240 devies *could* sound as good....or better?

Thanks ZM...

1.circ ............................................................................................. uit

2. strictly depending of taste ; to keep it short - 240/9240 are generally sounding more SE*-ish

* just in case , that means Single Ended

got it, thanks ZM. BTW (means by the way) I like the sound of SE, so that's good too!

I was checking out your blog....and your "koan" (guess that supposed to mean "clone"??)

Is it an...F5? You say it's better than an F4. Or is it a kind of hybrid?

 

[Zen Mod]

it's obvious you are just checking ........ not really reading 😉

as written here :Papa’s Koan (M)2 , an amp for living room | Zen Mod Blog

One of previous occasions of thrown bone is Papa’s Koan amplifier , pretty well presented at diyaudio.com in these two threads : Papa’s Koan ….. was Papa’s Surprise and Babysitter for Papa’s Koan .

so - you're having a pointer to thread about first Papa's Koan amp (there were many , prior to that , but not amps ) , where - in post #2 , you have link to K?an - Wikipedia, the free encyclopedia

these two amps are jewels per se , so not really comparable with any other
