I have just played 3 festivals back to back and used the Aero along with lending it to other DJs to play on for the festival.
It was connected via RCA to a spare channel on the Pioneer mixer CD Channel and then balanced the gains to make the same output volume as the CDJ playing. When using the Aero though there was a noticeable drop in sound quality compared to playing with CDJs. It was like the mids were somehow thinner and that the volume was less even though the gain level was the same. The last festival I played I tried to test it a bit more mixing between a CDJ 900 and the Aero across the mixer and back to the CDJ 900 and back to the Aero, 1 song 1 song, and all my friends agreed the sound was slightly better when the CDJ was playing.
Is this possible?
