In my den I typically listen to the speakers at a volume of around 65 to 75 decibels on my couch about 2 meters from the speakers. I rarely, if ever, hit 80 or 85 decibels. Since my KEF LS50s have a sensitivity of 85 dB/W/m, and my listening volume is always below 79 dB at 2 meters, would I gain anything (pardon the pun) by using an amp that delivers more than one watt? On paper it seems like even these "hard to drive" KEF LS50s wouldn't need more than 1 watt to deliver 82 dB at 2 meters? Is there more to it than just the sensitivity, listening volume, and wattage?
In the manual, KEF says I should use an amplifier that can deliver between 25 and 100 watts. Is that just because the average user is further away and/or listens at louder levels?
I currently use a pair of monoblock Amp Camp Amps (a wonderful little DIY Class A amp designed by Nelson Pass), and they deliver 8 watts per channel. Is there any chance that I could damage the tweeters by using these "under-powered" amps, or is 8 watts per channel more than enough power for my listening levels? Even if they're safe from damage, would a more powerful amp sound better? People always use words like "authority", "grip", etc. to suggest that more watts equals better sound. Is there any science behind that?
Photo attached in case anyone would like to see the current setup.
