A good power conditioner and power cords. Drops the noise floor. Lower noise floor increases signal to noise most dramatically at low listening levels.

Which Component Has the Greatest Affect on Low-Level Listening
My Benchmark HPA4 preamp had the biggest positive on low level listening. It has a volume control with 256 settings and it is quieter than any other source component you will use with it. Once of the reasons I got it was for late night low volume listening. It has exceeded expectations on all fronts. |
Speakers. You probably need a powered sub or two practically with most setups to sound best at low volume because our ear sensitivity drops off and we do not hear nearly as much as we do at louder volumes. Equal-loudness contour - Wikipedia |
mapman linked https://en.wikipedia.org/wiki/Equal-loudness_contour You want a system with automatic ’loudness’ circuit. It is completely misnamed, it is a ’low level boost’ to boost bass progressively as volume lowers, (boosts highs also, less importantly). Maintaining bass at low volume will maintain involvement with the music, otherwise it becomes background noise. To compensate ONLY when listening at low volume. Raise the volume, eliminate the boost, otherwise the bass is too prominent as well as the highs will get screechy. As you raise the volume, you want the circuit to automatically/progressively reduce/remove the ’loudness’ boost, back to normal for normal or louder. This unit has a built in automatic fletcher munson circuit, and remote volume, remote balance, I wouldn't live without it. https://www.ebay.com/itm/Chase-Remote-Line-Controller-RLC-1/254708363331?hash=item3b4dcd3043:g:huIAA... Vintage receivers have ’loudness’ filters. |
