I don't think there is anything to really solve? I have similar problems when I mix on the smaller speakers in the video studio - I simply can't trust these for making decisions on the less than 1K content. In my audio studio - the mixes work on the small ones in the video studio, and the ones mixed on the IEMs I quite like work pretty well. I have a pair of Sennheiser that sound great on playback, but mixing on those is dangerous? When you say 'quality' - what exactly do you mean?
