I can only offer what I experienced first hand. I had a large pair of Usher floor standers and even with beefy, mono block amps the speakers needed to played at moderate volume to sound full and have proper bass. I now have Tekton Lore speakers that are efficient powered by a Rega integrated amp. Difference is these speakers produce full sound, good bass even at low volume. Being in my 50s my hearing is not what it use to be and I try to avoid moderate to loud music to avoid ringing in my ears.
Loudness or high sensitive speakers?
Loudness is used for low volume listening.
But high sensitive speakers are also said to be good for low level listening.
So either I can have speakers with, say 89dB sensitivity and use a amplifier with a loudness button or just have really sensitive speakers.
And both ways will sound good at low volume. Right? Just as good? Or...?
