Auditors are great speakers and do very well with Linn amplification. If you can find a Chakra 2200 used for 2k, pounce on it. For that matter, the Auditors will sound very nice with an LK 140 for only $750 used, though in that case you will have to deal with getting BFA adapters (mine cost me around $40).
If you like tube amps, you probably should avoid the Linn 2250 or 5125, as these are much leaner than the other two amps I mention, which are quite warm.
