McIntosh MA8900 DAC.....What chipset?

You can call McIntosh and they will tell you.  They will direct you to the Head Tech on the factory floor to answer your questions.

I believe it's a TI/Burr Brown chip. Could also be ESS or AKM, but doubtful it's anything fancy like an Analog Devices.

Thanks guys! I am debating upgrading with DAC like a Lumin Streamer (T2) or something else for pulling those "duties".

That was quick. I just heard back from someone and the chip set that is in the DA1 Module is the ESS Sabre ES9016. That seems to be a very capable chip set.

Shipping now is the DA2 which can upgrade some of the new(er) McIntosh units and I was told that has the ESS Sabre 9028pro which is definitely a big jump in capabilities as well as HDMI.
