I heard Einsteins quite few times and I also know the Graafs 20 ... but I never had the opportunity to hear them with Mewrlins. So, no direct answer to your question - and anyway, fairly soon you will be able to find it for yourself ....
My guess though is that you will not get big improvement with Einstein over the Graafs. I do not believe that there will be any improvement at all. It will sound differently though ...
I find Graafs excellent amps and I wouldn't be keen to replace them.
