Hi Sky, If you go to the Amp/Preamp forum and look for the heading: Opinions on Conrad Johnson CA 200
There is a post by Crozbo who likes the CA 200 with his Penaudios.

Then there is a review of the c-j CA 200 with Penaudio Serenades at the address below.

I have the audio research vsi55 integrated with my penaudio charisma/Chara and I love it.
