I have not measurements but the difference has been appreciated by family and friends.
It is very evident, in my two systems. The two systems have
clean power, now cleaner than ever!
The
modern soundtracks I have has DR <
10 dB. I do not have DR from the films but yes from the soundtracks. The last:
Queen - Bohemian Rhapsody Original Soundtrack (2018) (HDtracks) {24-96} [FLAC]
