New to hifi... question about Lumin T2 and Roon

Hi, guys (and gals). I’m brand new to hifi. Just recently purchased a Lumin T2, Luxman 590axii, and Franco Serblin Essence speakers. I’m at the point in my life where I can finally afford to have a little bit of hifi fun. Always wanted to get into this area, just never had the space. Anyway, I’m hoping I made a good move with the equipment I put together. Everything is still brand new and I’m in the process of running my amp and streamer, 24/7.

Anyway, I’ve done a bunch of searching but haven’t found anything truly on point (although I’m sure I’ve just missed it). My question is how do I hook up my T2 to a Roon Nucleus (just ordered it)? Do I hook both devices up to my router or do I just hook up the Roon Nucleus and then USB connect to the T2?

Also, does it take a while to burn in the FS Essence speakers? They seem a bit "tight" right now and bass seems to be lacking. Since everything is brand new, I have no idea what might be causing this issue, other than all components need time to burn in and settle in.

Thoughts?

Thanks.

Bill
