Hello, I've used the 2.5i as well as the 2.9 for about 3 years now and have had excellent results w/ a multitude of amp/preamp combos. the amps that seem to work ther best are those typically w/a high dampning factor. The Bryston 4BST has very worked well . Another amp thats worked very well and typically found well under $1K here on Audigon is the MUSE 160.
One thing I've found is that a decent Tube preamp goes a long way in tamming the highs in the NHT's , suggestion here might be an ANTHEM PRE 1L or even better A SONIC FRONTIERS SFL-1 both can be had around $ 500.
Hope this helps
