I run them with a Moon i-3 integrated and they are just great. I will purchase a good SET when the piggy bank is full and improve on the Moon CD-1's DAC with either an Eastern Electric DAC+ or an AudioNote DAC. Moon is fab with the Essence speakers. I understand the Nelson Pass J2 is as well if you want to go with solid state. The speaker can harmonize well with both types of amplification.
