Pani -- OK, the amps you're considering are top players! BUT having tried many of them as well as ATC's here goes. Trust me on this one :)...
a) Einstein: forget it. All are underpowered (even the big stereo). Great products, the integrated is the best IMO.
b) Graaf: forget it. The only product that *may* drive it is an old 200W otl. It now probably costs more than a Ferrari, so buy the Ferrari instead, it's a better deal. I love Graaf sound -- on horns.
c) Octave: another star sonically. Forget it. Only the big monos *might* work (called "Jubilee") and they cost a fortune.
d) Why don't you simply purchase a pair of S-Line RG4? You can probably buy 3pairs for the price of the big Octaves! If you already have these (if so, why are looking?), go for the classA Kraft.
e) DOn;t know the Audio Space. Maybe that's your ticket if the 50W rated product drives yr ATCs. The others don't. They may sound as if they do, but you're losing musical energy and information. NOT what you bought those ATCs for!
