First room: Focal and the 432 Evo Streamer/server.
432 Evo is a Belgian company.
They produce streamers that convert 440Hz into 432Hz on the fly.
It seems that 90% of the listeners prefer 432Hz as it would sound more natural.
Italian composers from the 17th and 18th century knew this already and composed in 432Hz I was told.
As hard as I tried, I couldn't hear a difference.
It could have been the Focal headphones, that might be not revealing enough.
I could switch as much as I wanted, but nope, nothing changed for me.
I want to hear this through a decent system, but so far I'm not convinced.
For the rest this was an interesting room, with Focal Sopras, Metronome Technology CD/DAC, and amps I hadn't heard of before.
The server has 2 Tb internal memory.
No SSD as they believe SSD cause high pitch distortion.
