I have used this power supply for probably 20 years or more, however due to future downsizing I am going back to an onboard power supply for my LP 12 to reduce the number of HiFi boxes! Previous to the Airpower I used Valhalla, and then Armageddon power supplies. In my system the Airpower is better than either. It produces a stable and large soundstage with more dynamics than either of the other supplies I have previously used. So good that in 20 years I have kept this, now very rare power supply in my system. Finally it needs to go to a new home!
