I have heard the Temptations at my dealer's on a lot of occasions for several years. Amps used include the Accuphase 50 watt class A stereo amp, the Boulder 1000 series monos, Lamm ML1.1s and the Siltech amps, the latter two tubed designs. If you have a big room and play them loud, a strong solid state or big tube amp will be needed. You may lose some bass control with the tubes, so if that matters a lot you should steer towards solid state. I will state, as a tube man who owns Lamms, that my pick of all the amps on them was the Siltechs, followed by the Lamms, both of which drove them to fine volume levels and sounded superb. You should probably check with your amp manufacturer, but my guess is that the Music Reference should have enough to drive your speakers and make great music, you just may lack the last bit of control in the bass but the bass you get should still sound very natural and full.
