Allready knew about Miyajima but did not know about cross ring coils..... nice presentation they have.

As for 489, I did some calculations and to get the same gain in a common source compared to a k170, I would need much larger Rs and also large Vdd, so I agree it would be noisier.... maybe it has other advantages I am not aware of.
