Modwright KWA 150 mono v. 1 KWA 150se w/Aerial 9

Hey. As a replacement to Classe CAM 350s driving my Aerial 9s, I am about to buy either 2 150s to run mono or 1 150se (can't afford 2). I am very familiar with both amps, but have never heard a side by side of 1 SE v, regular 150 in mono. Can anyone discuss the difference between the 2?

Also, for anyone who knows Aerial, i am somewhat concerned that 150w may not be enough to really make the 9s sing. Anyone have any insights there?

Thanks in advance.

I would talk to Dan Wright, at Modwright, and get his thoughts. Dan is a great guy, and always helpful.
