Upgrade-itus: Classé DR-9 vs. MF A3.2?

Hello Audiogon and your infinite wisdom.
I have the option to buy a Classé DR-9 to replace my MF A3.2 integrated. The MF IS 185w @ 4 ohms the Classé 200w @ 4 ohms. I'm driving Dynaudio Contour S1.4 monitors.

Thoughts? I'm sure both are good, what will the sound differences be? Dynamics, hi, lo, sound stage, warmth?

For the short term the A3.2 will be pre-amp.
Thanks!
Andy
