Thank you for your responses. Jordan, as you stated (and as stated in the Soundlab FAQ's) the Soundlabs have raising impedance in the lower frequencies. I've always thought that power amplifiers in general have no trouble driving speakers with higher impedance. The problem is often with low to very low (like the 0.3Ohms(!) in case of the old Apogee) impedances. So why would the Soundlab sound relatively louder in the treble with a solid state amplifier?
