Sonus Faber Electa Amator 2 vs Eggleston Isabel

What's the rest of your system?

The Andras are very good speakers and they will tell you what your electronics are doing. I do not know how they would sound with your Krell 300i and Sony SACD.
I would think with those electronics you might want 'forgiving' speakers that won't make the electronics sound so bright and forward, as those components in particular can sound.

I used to own the original Electa Amators and now own the Guarneri Homage monitors. I can say that the Electa Amators would fill a room with amazing ease and are true to the music. They are beautifully made. They produce exceptional bass for a small speaker and disappear well. The adjustable height stands are a dream to use allowing infinite changes for room dimensions and seating height. I think the 2's with the ABR are easier to drive than the originals. The new tweeter may not be the same as the Esotar in the originals. I really loved mine.
