Thanks to one of the diyaudio.com member (LC) I was able to solder this simple IPS board. It is the basic CFA design, with AC ground coupled front end. Very high speed and low distortion input stage produces well balanced smooth sound. Offset at the output of the amplifier is well maintained close to 0mV, temperature variation is very low and does not exceed more than a few mV. Some more info is coming.
