You do not mention your budget or the size of your room or any other parameters. The AudioNote AN-J/K/E are designed for just this purpose -- although they do the best in corners. I have Zu Def 4s within a couple of inches of the rear wall. All of these are tube friendly. Classic Linn is great, but not that tube friendly. If possible, you should audition at home -- or at least have a return option.
Speakers good for close to wall placement
There are quite a few speakers I would like to purchase, but I need to be realistic. I will need to find some speakers that perform well when placed close to the rear wall. After that choice I can move on to selecting the proper integrated amp to drive them. Any suggestions on which speakers work well near the rear wall?
