Many, many thanks, Streborx2. Got the job done with your helpful instructions, but I forgot to take photos as I did the 'operation.' The HAP-Z1 works flawlessly, and I didn't even lose the sample music that came installed on the HDD (making me wonder: there must be some internal memory somewhere that can hold firmware + some music!). Anyway, I'm beginning the LONG project of ripping about 1300 CDs into FLAC files using DB Poweramp version 16. So far, album art and cataloging have gone great; it's preselected settings make sense for classical music collectors, of which I am one. So, multiple recordings of the same symphony, or collections spanning several discs, are no problem with default settings. whew!
