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?

Well boys, maybe the audio gods are shining on me. Allan hooked me up with a great guy that is selling me a 1 year old ZH270 with NOS tubes that have been cryogeniclly treated. Thanks again Allan. I should have it next week and will let you know how it sounds. Thanks to all who have contributed to this thread.
Great score, slowhand! I would be very interested in you reactions to the Supra/Berning combo. Let us know, please.
I should have the ZH270 next week sometime. Keep an eye on this thread and I will post my impressions.
And Slowhand I should have a Sarah within the next few weeks, we shall compare notes!
Well guys, I have had my ZH270 for 3 days now and I can't stop listening to it. It is everything you said it was. I am getting off the crazy merry go round of buying equipment and am going to sit back and start enjoying music. I am where I have been trying to get to for the past 25 years!
