Strangely enough, when I went to their site, it links to their Ebay site. And that is the message i received from the Ebay site. Maybe i would write into the directly and see what happens.

That was 2 years ago before Merus was acquired by Infineon.

This is MA12070P, with the I2S interface. Later I did another revision of PCB with Schottky diodes added to protect the IC from overstressing (you can see results on the photo attached).

The sound was good thou, I still have a couple of PCBs and IC's to play with. However, I did not compare it with my TAS5548+TAS5162 amp.

Hi, my name is Mandy, an employee of SMSL.

This is the link of SA300, can be sent from the EU:
SMSL SA300 Digital power Amplifier – hifiexpress1

This IC is very precise, not suitable for DIY.
