Good speakers with the NAD M3

In my second system I have NAD M3 Amplifier and PSB Imagine B
Speakers and sound is good. Are there any other good speakers
that would sound great with the NAD M3.
Thanks in advance on your opinions.
I have used Harmonic Technology Pro 11 Plus, Audioquest CV-8 w/DBS pack and Audioquest Type 6. All sound excellent with the NAD M3.
I have Usher BE-718's powered by the M3 plus a pair of JL Audio F110 subwoofers and it sounds really good. Works out well because I use the M3's bass management feature to roll off the lows to the monitors and go full range to the subs in stereo. Lets the Ushers do their thing without being overdriven at high levels.
