AGDR has done it again and taken his new super Cmoy's design using the new TI OP1688 chip to the next level. He has added a second OP1688 to double the current capacity!!
 
I will be building on up next week and will be able to compare to the original cMoy and AGDR's new OP1688 cMoys!

Whoa nice! Interested to hear what they sound like.

I have built three of them so far and all three are very nice.
 
I use them with Beyer T90's, ATH M50's, Beyer dt1350's, and all play well.
 
The latest third generation has more current capacity.
 
Side by side with an O2 you cant tell the difference.
 
I have posted my review of the sound in this link at diyaudio.com
