Well after readying your first post i had alread cracked my knuckes to post asking what you did. Clever to break it into 2 posts to pique interest.
All you did makes sense to me. I just upgrade the power supply to my DAC with Farad but it is quite a bit more expensive than what you chose. I’m impressed you did this all for $1k.
Well done,
PS I think the things you did are independent of wired vs wireless.
