The differences are not consistent. I don't know if it's the formats - because I have not heard two recordings using identical chain on two different format. I say identical because different mic preamps have different sounds, and if you believe in cables, the recording engineers I know all believe that even the microphone cables have different characteristics, and different combinations of microphones and cables sound different.
On this one, the differences were quite pronounced. There were two recording chains - two different mics were used: the B&K 4006 on the analog chain, and the Tonecraft 2013 on the digital chain.
thanks, Gary. Makes sense.
