Integrated Amp recommendation


I have a 2 channel setup in my home office that I am considering upgrading. It consists of a vintage Yamaha CR-2020 (bought new back in the 70's-but getting a little long in the tooth), a pair of Polk Lsi9's, and a Velodyne sub (which is off most of the time). This setup works very well for me. Although I listen primarily to jazz, (CD, vinyl and some digital) I enjoy many types of music. I am currently considering the following integrateds to replace my aging Yamaha:
NAD M3 (used), NAD C375BEE, Anthem 225, Yamaha A-S2000, McIntosh MA6500 (used), and Cambridge 840A v2.
I am leaning toward new vs used as I don't plan to upgrade anytime in the near future. My problem is that I live in an area that I can't audition ANY of the above.
I would appreciate any recommendations.

I'd go NAD. I gave mine to my now 19 year old son and I miss it like crazy. I'm running a tube integrated now, but if I ever see a 375 come up used for a good price, I'm going to grab it and put it in my closet to run in the summer time.
I appreciate the compliment on my CR-2020. I should have explained that I plan to move it to the bedroom where it won't get as much use and hopefully extend it's life. I am looking to replace it in my home office setting with an integrated that will provide similar sonic performance (that "70's Yamaha Natural Sound"), but require less maintence than my CR-2020. Thanks
I appreciate the responses. What I am looking for is an integrated around 2K or less, with the open, airy, and what I percieve to be uncolored sound that I get from my CR-2020. I also would like to have tone controls or some form of eq as my office doesnt have the best acoustics and some source material requires a slight "tweak" from time to time. I just have no idea what may most closely match my Yammy in sound charistics.
