Nice system Freo-1 Must sound awesome..
I recently purchased a Woo Audio WA22 headphone amp to go with a pair of Sennheiser HD800S
headphones I already owned.. The rest of the system is a Mac Mini M4 and a Denafrips Area 15th Dac..
Alternate system is a Mytek Brooklyn Bridge amp and a pair of Hifiman Ananda headphones.
The WA22 is still breaking in but so for I'm very happy with the sound quality I'm getting.
