Hi

I think from memory, I don't have them anymore, that the DIN socket allows a balanced connection whereas the phono is single ended.

I used mine with the 101B originally but much preferred a Classe preamp that I used for many years. I also used a 208 that was good too. I don't think there is any special symbiotics between a 101 and M2 and your DAC probably works as well.

The M33 was a much newer design and I'm not surprised at your findings. I changed to DSP speakers that are more dynamic.
