@southofdallas This is exactly why its a good idea to use speakers that are easy to drive. You don't have to sacrifice any resolution to have easy to drive speakers. Lower efficiency speakers tend to have something called 'thermal compression' which is caused by heating of the voice coils. The higher the efficiency of the speaker the less compression you get.
When a slightly lower power amp is driving higher efficiency/easy to drive speakers you find you can get the same effortless quality.
I always associated 'air' with ease and space in the highs. I've not heard of it used in the context that you do; probably a topic for another thread.
