I don't think anyone answered this question when I asked many pages ago.
The iPhone/iPod connected to M8 via supplied cable and headphone connected to M8 using the balanced plugs will allow fully balanced sound?
I asked this because CLAS db plus MK3 needs the additional RSA adaptor from dac to amp plus another RSA adaptor for headphones.
From what I know:
Yes, the M8 extracts the data from the iDevice, processes it through its DAC, and output the balanced sound through its amp to the balanced plugs.
The CLAS does the data extraction and DAC portion of the M8, and requires an AMP to do the AMP part of the M8. Which is why you need an extra cable to connect the 2 devices. Then the AMP you are talking about uses the 'RSA' output. For the M8, you have a choice as to what balanced output you want.
