I agree with the KEF LS50 recommendation. I think it would be a great match. By the way, the NAD 375BEE is an excellent integrated amp, but it's generally known a warmer amp and may not have the detailed highs that you are seeking. Another thing to note is that the sound of the 375BEE improves dramatically when you use a set of good interconnects between the pre-out and the power-in rather than leaving the stock metal bars in the signal path. I was stunned at the difference that this made. You could probably get much closer to the sound you want with some good, detailed interconnects.
