Wolfson ’s ARE enjoyable and it does Room if that’s your thing.
Any differences in the streaming.engines is so minimal that I am not concerned.
Lumin D2 or Aurender N100H
Both are discontinued 2015-2018 models and currently selling at a similar price ($1200) used. Features wise:
I'm less concerned about the differences in limited features and more curious about your preference or pick in terms of (1) sound quality, (2) app usability as a streamer and (3) should I be saving up (up to $2500) for newer models if the upgrade in sound is justifiable? I’d appreciate your thoughts, especially from those with experience using both.
