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?

Fosse: It was in fact the Final Cut OTL amp. Sorry about the HUGE delay in getting back to you, I had forgotten about this thread and have been deep into DAC comparisons and reviews.
I ended up not buying the Einsteins, the Graafs simply outperformed them in my setup. The Einsteins sounds thin compared to the Graafs.
To Fosse: What was a defference between you Graafs mono and Einstein mono ? Thanks
