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...

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

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

Quote:
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
