OK, sigh... I have to admit. The M2s sound even better with the sub turned on. The HDCD mode does sound a tiny bit more clear than any of the regular decoding modes. Is that the placebos again ?

It somehow seems wrong to be able to switch from HDCD to regular CD at the receiver. Shouldn't it be a different track or something... or is it one recording with a non-standard digital feed and receivers normally only decode the lower res information ?

Enquiring minds want to know.
