You resolved the confusion, when not sure to get active or passive, get both. 😀
That is only partly funny because I did the same thing. Active in my HT and desktop, passive in the man cave. They are all fun, and different.
@brianlucey got me thinking about my next build. I never gave Atmos in headphones much thought. I never gave Atmos and analog much thought. His posts made me think. I think I want to build an Atmos/analog tube based headphone rig as my next "system". Jim Fosgate and Black Ice audio collaborated on a SOA headphone amp that they demoed at CEDIA 2022. Will see what happens once it is released. The FOZ says it is his finest creation, how everything he has done before has led him here. I have never done tubes or headphones seriously, hopefully this will be a good introduction to both.
