Noob

Welcome.
I understand if you feel like a noob now, but that soon may pass as you learn. I was feeling the same when I started this amazing hobby and joined the forum years ago. It can be intimidating being on a forum with extremely knowledgeable and experienced people, and many are world class designers, but they are all here for the love of diy audio and willing to share and help, even noobs. Google is also your friend. Initially I Googled everything, like where to solder the red and black wires to a RCA connector.
Today I have a most satisfactory hifi system I listen to everyday and I did diy everything, from the DAC to the preamp, to the power amp, to the speakers.
Enjoy the ride.
