Setup question


A brief setup question if someone doesn’t mind helping me out. In my family room, I currently have a 5.1 setup with a HK AV receiver, 2 JBL towers and JBL everything else (which will be upgraded to PSB sooner than later). I wanted to add vinyl to my family room setup but my receiver does not have phono in. I bought a nice Rotel turntable and NAD amp that can be used as a pre, power or integrated amp.

My question is, what is the best utilization of this equipment? Should I go turntable > NAD (pre) >HK? Or should I go turntable>NAD (integrated) >speakers and use the speakers for both setups with a switch?

Thank you in advance for your help.

@mesch  That's a great idea..I may have to start doing that as well to really learn what's out there. I'm blessed to have two extremely good vintage audio stores within 30 minutes of my house as well. It's made this whole mission significantly easier.

I originally only did 2 channel and I felt it lacked a bit in the bass..so I turned up the bass on the receiver and tried to get settings where I wanted them (for the record I favor brightness overall so go figure) but couldn't get what I wanted so I added a small powered sub. I don't have it turned up very much. In fact, I kept checking to make sure it was on because the level I had it at made it faint..but it added the exact amount of bass I was looking for on my records. I can just turn up the level when I watch a movie I suppose. But when I get the PSB's, I'll try two channel first..I can always have the sub plugged in and leave it off until I put on a movie.
With music one should not hear the sub, the bass extension yes but not the sub, at least not to know where it is located. 

Enjoy!
Thanks @mesch ...the advice is very much appreciated. I'll update you once the psb's are hooked up but so far so good.
Lots of quality equipment will get you there. I just wanted you to know you should not settle for anything that is not crystal clear, and think thats the way it is. I have a nice NAD T878 and B&W HTM 1 Center Channel and the 805s.
