You always need to compare devices at the same level of loudness. The DL III obviously has a higher output level than the Ayre, but it doesn't mean it has better or worse sound because of that. Just a stronger output signal coming out of its output stage. It is not necessarily a problem in any unit - only a difference between them.
You need to listen to each and adjust your volume levels accordingly for each so they are producing the same singnal strength out of your pream and into your amp and out of your speakers.
