Music Reference RM200 or David Berning ZH270?


I am interested in both of these amps. Has anyone out there heard both of them before? The associated equipment that I would be using is Gallo Nuclius Reference speakers (88db efficiency), Supratek Syrah preamp, Granite Audio 650 CD player, MIT 330 and TG Audio IC's and MIT 750 plus speaker cable. Can anyone tell me the differences in these two amps, or your expriences with them?

Slowhand,
I have owned a Berning 270 and now own a Berning Siegfried amp. Since you have already committed to Berning, I would recommend several "tweaks" to enhance the listening experience.
1) Address microphonics. All Berning amps appear to be susceptable. I have used Halo's on the tubes and would recommend Symposium or Stillpoints underneath the amp.
2) A good power cord is a must. Try TG Audio or Shunyata.
3) Definitely tube roll. The Svetlana tubes are pretty good but you can sweeten the sound with some NOS tubes. Unfortunately you can't roll the output tubes.
I have found the combination of the above factors to have significantly improved the sound. Overall improvement in bass,less sibilance,sweeter midrange,increased clarity.
Enjoy listening.
