Recommendations for used/vintage integrated for vinyl

Hi, 
you guys have pointed me in the right direction a few times now and totally appreciate the help.  I sold off my pro-ject and music hall integrated that were not playing nice together and I am looking to buy a used integrated that can push my Dzurko Jaguar speakers a little harder.

Long story short I sold best components to pay for grad school a few years ago. That rig was a hodgepodge of really nice stuff mixed with my guitar center fire sale gear.   99% of my listening went Stanton direct drive dj turntable (bought on clearance for around 100 bucks), a Shure DJ cartridge (don't remember which one), 50 dollar ART phono preamp,  into a Mark Levinson No.380 preamp,  Krell KSA 150 power amp, Dzurko Jaguar speakers.  

Even though the turntable and phono preamp was pretty bottom end from a chain guitar store, all of my records sounded good with some real heft to the tone, by comparison the music hall with pro-ject was thin and revealed the imperfections of my records instead of enhancing or allowing the music to just play. 

I am about to get a Thorens 160 in excellent condition in trade for some of my unused recording studio gear and I would like to get an older integrated of at least 100 watts 8ohm to go with it.  I would like to stay away from brand new because I would like something  with longevity and will be worth roughly what I paid when and if I decide to sell. 

What are some good integrated amps for someone who 1) only listens to vinyl 2) listens to a lot or rare and original pressings that are not available on 180 gram vinyl.   

Part of me kind of wants an old Kenwood KA-9600 receiver since they seem to be held in high regard and were made when vinyl was still the top medium.  What about the 9100 integrated?  any good?

Years ago the person who gave me the Levinson 380 recommended that I should consider selling it and buy a Music Fidelity A300 since I am only interested in vinyl.  How is this as an options?

anything else? I would like to spend around 550.00 for a used integrated since that is what I sold my turntable and integrated for but I could certainly go higher if there was something much better. 

Thank you,
