Where to get advice on a new system build

Hello, 

I’m jumping back into stereo stuff again after a long hiatus, I was in the high end industry for quite some time before I changed careers.

I haven’t heard anything in 5+ years, so listening is going to be first. 

The question I have is, who can I work with to help me sort this out?  I have no idea what I will end up with, and I would love to explore for a bit, subsequently, until I listen to some equipment I couldn’t commit to a product line / dealer (if that’s what I will need to do).

 I know that there are dealers on this site, and I would like your thoughts too.  I was a dealer and I thoroughly enjoyed helping people with their journey, when they picked up something elsewhere I felt a little bad.

I have a dedicated and treated room, and I would prefer used equipment.
