Re: High quality non amplified system
Hearing fatigue is also caused by distortion. Listen to something at a mid level volume wise that's either a really compressed recording or somehow distorted. Then crank up something that's really cleanly recorded on a system that will play it with cleanliness. You're going to feel fatigue on the distorted system first, even though it is being played at a lower volume. The high volume will also cause fatigue, but, from experience, you probably won't notice it until the music is done. That's my 2 cents on that one. I say amp your speakers for cleaner sound and make sure the speakers you get suit your listening habits.
