Would the 300W CJ ART 300 Monoblocks be too much for my Avalon Ascendants?

Looking to replace and upgrade my amps (one of my Sonic Frontier Power 3's - which I loved and have had for nearly 20 years - died) and was looking at Conrad Johnson Art 150 and 300 monoblocks (I have a CJ CT5 pre-amp). My Avalon Ascendants are rated up to 200W so was wondering if 300W monoblocks will be too much for them? Thanks in advance for any help on this one.
