I'm curious to see how the 1723s compare to those, with a similarly professional review.
They are smaller, cheaper, yet on the Arendal website show rather similar measurements and even flatter frequency response, but seem to have a wider dispersion below 1KHz (not sure what that means, and it's difficult to read their graphs). Also the Impedance seems like it might dip to 3ohm at a few points, so wondering if a receiver could deal with that or not.
