Einstein The Final Cut vs. Graaf GM20 Mono


I have a pair of Graaf GM20 (mono bridged) driving my Merlin VSM MXe. Preamplifier is Hovland HP-100.

I am thinking of buying a pair of Einstein The Final Cut monoblocks (last model) but I am not sure they will better my Graafs. Has anybody compared them to the Graafs or had them driving Merlin VSM?

My uncle had the Einstein amp, he thought it was ok, he also had the Graaf Modena, which I bought from him. He never mentions the Einstein, but wishes he had not sold the Modena. Hope that helps. I am looking for a another Modena so I can bridge them.
Thanks a lot Audiofun. The Modena is the same amp as GM20 (just an other color) so this is nice to know.

You say "the Einstein amp". Was it The Final Cut? OTL mono amplifiers?
Not that there is anything wrong with the Einstein, and I never heard it, but isn't the Atma-sphere M60s (or Joules) on your short list for the Merlin's? Nothing I have tried has worked better with the Merlins - they do seem to be designed as a good match for OTLs in general.
Sure Pubul57, the problem is that I'm living in Norway and there is no dealer for Joule og Atmasphere here. I can buy from outside Norway but then I have now chance to hear the equipment at home before buying. I have decided to try the Einsteins at home, they are coming next week. Thanks a lot.
