Integrated amplifier recommendations, Please


Hello everybody. I am new to your board but have browsed the site countless times and from what I have read, I will value your input greatly. I have gotten the kids through college and now it's my time to play. I am a music enthusiast and have had and still do have a bunch of equipment that I use. It's not bottom of the line stuff by my standards, but it's time to move up.
I have never owned a dedicated amp/pre-amp or an integrated amp and I would like to start out by getting a decent used integrated, middle of the road, under $500.00 if possible. I have been doing a lot of looking on the web and it seems like NAD or Adcom might be a safe bet.
Am I on the wrong track?
Music interests are Jazz, Classical, Knopfler, Ambient and Floyd.
Speakers: Infinity Ref Five, Pinnacle, DIY..Looking to upgrade here too.
I thank you all very much in advance!

You are definitely on the right track.
You will want to take into consideration present and future speakers, but NAD will work for many speakers. You will obviously get more power for your $500 if you buy used.

There's an Audio Refinement Complete integrated currently for sale at $450 right now - and its sound quality is certainly better than "middle of the road", that's for sure!
