Can't decide

I run Monitor Audio Gold (250?) with a Parasound A21+ and couldn’t be happier. Margo Timmons has never sounded lean on my system :-). Haven’t heard the Dynaudios but love the synergy in my system. Be My 2 cents worth. 

DynAudio, outstanding speakers. Very neutral and impactful, accurate. Will reflect the electronics you put behind them.

My Evoke 50's would sound excellent with the Parasound. The treble is more laid back and needs an amp that can waken them up. Class D really controls their immense bottom end too. 

I know this isn't the question, but I'd go with Fritz Carbon 7 Mk. II SE's. Search around about them.

Atalante 3 monitors, designed by the guy who headed the team that designed the Dynaudio Contour 20. You'll save over half going for the Atalante 3.

All the best,
