Thanks! Utopia is out of my reach. I asked because manufacturers often refer impedance (low) first, as a key feature for drivability by portable players. Sensibility should ultimately express the sound pressure level for a given power value, and the lower the impedance the less effort the amp has to do to accomplish that? Well, whatever ...
I called the local representative for Focal, they should have news by the end of the month, maybe a good time to make a deal on a pair of Elears no?
And about other options on par? There are so many to look for...
