The specs for the Nucleus suggests up to 10 000 albums and the Nucleus Plus for more than 10 000 albums. I am correct in assuming the amount of albums includes those added to library from Tidal as well as those on a hard drive?
Yes you are.
10.000 albums!? If you listen one album per day
you are done in 27 years
Mate, I’m just quoting Roon’s stated specifications. Plus is over 10 000 albums.
