Hi, Alex, I think you are correct in this. I have four DA-20MKII machines and I believe they are 16 bit which was the bulk of the DAT usage. It would be extremely helpful if someone who was closer to the HR DATs than I was could post a list of all the HR variations for DAT, DTRS, and ADAT. All of these started out as 44.1/48 ks/s and 16 bits, but they all grew. I just am not aware of all the options. I do know ADAT went to 20 bits (I have an XT20). If whoever posts it agrees, I would like to place it (with credit) on my blog site www.richardhess.com/notes/ Thanks!
