Hi all! I originally posted this question back in April and believe it or not I still haven't purchased an amp yet. I did do a direct A/B comparison between the Krell and the Classe and found I liked the sound of the Krell better. It definitely has more bottom-end slam than the Classe. Don't get me wrong. I think the Classe is a good amp but I preferred the Krell over it. Lately, however, I have been hearing really good things about the Plinius 8150 integrated amp. Any more thoughts on this amp besides the ones already posted? I really appreciate everyone's input in this matter. I am still looking for the "perfect" amp to complement my system which by the way, consists of NHT 2.5i's and a Sony ES cd player (which I am looking to upgrade also in the near future). I listen to a lot of jazz- both traditional and contemporary, and like my music somewhat aggresive with good, tight bass. Again, thanks for your thoughts and please give me any additional input about the Plinius amp!
