Ayre AX-7e with KEF Reference 1s or LS50 Metas

I'm downsizing and plan to sell my Ayre QX-5, KX-5, VX-5 Twenties that I've used with KEF Reference 1s.  I'd like to try my Ayre AX-7e integrated amp (60 watts 8°, 120 watts 4°) with either the Reference 1s or LS50 Metas.  I really like the AX-7e with LS50 Metas but haven't heard it with the Reference 1s. -- wonder if 120 watts is adequate.  Any suggestions?
