More power for better sound at low volumes?

Yes big power = nice low volume listening. I also totally agree with Lloydelee21 that lower noise contributes to low listening accuracy. With each upgrade I've made, all of which lowered the noise floor, the volume knob was reduced for much of my listening. Before replacing my 500 watt amp with 1200 watt monos I suspected I might have to play at least at a moderate level to perceive a balanced performance. I couldn't have been more suprised when the higher powered amps sounded great at well under 1 watt on the meters. This is no doubt due to the lower noise and balanced power delivery high power amps can deliver at all levels.

I have found the most engaging sounding amplifiers to be those with lower power. Just my experience.

What do you want the system to do better at low volume? Do you have an SPL meter to measure what you consider low volume?

A good set of headphones is your answer.

A lot of vintage gear used to have loudness controls and other tone control features that due to how the human ear works were useful at low volumes sometimes but required manual interaction to activate/use.

Its possible that this could still be part of an amplifiers design, ie internalized auto equalization in essence for the purpose of optimizing sound at all volumes.

Sounds like at least a couple makers might do this but do not know for sure. Some might advertise as a feature or some might keep it under wraps so as not to offend audiophiles that object to equalization solutions but like good sound at all volumes.

IF done well, I think this could be a good thing/feature if any makers want to fess up?
