I have Maggie MG 1.6's - need amp advice


I have Magnepan MG 1.6QR's and an Audio Research LS-8 PreAmp but only an Acurus A-200 power amp. I need to upgrade my amp to something twice as powerful I have been told (400 -500 watts) in order to really hear what the Maggies will do.
Since I have a tube preamp what would be a good SS Amp and should I go with MonoBloc's or . . .?
Tube? SS? Need help. I have heard that Classe amps are great with Maggie's. Any help would be appreciated.
Also of note - I have a Velodyne 18" powered sub (1250) watts for the sub.

I think your Acurus has enough power. There are better sounding amps but if you like the sound of the Acurus I suggest you save your money.
I believe your amp has 300W into 4Ohm which will run the Maggies fine, it depends on how big's your room and how loud you listen, if an average size room your amp's big enough. Tube pre and SS amp is a good match and lot of members reffered. I've this combo to run Mg 10/QR with good results. Cheers.
For years I used Bryston amps,Audio Research pre's,and 1.6's with very satisfying results.There seemed to be a natural synergy between Bryston amps and Maggies.This maybe urban legend,I was told when Magnepan and or Bryston went on a road show they used each others products to show case their equipment.Actually, the guy to talk to is James Tanner,he's Brystons point guy.He sold me my first pair of Maggies back in the 80's.
