I have a new Daystate Revere .22 regulated that was bundled with the 0dB 110C moderator from AOA.
For me, the 0dB 110C was quietest compared to my Sumo .25 and Huma MOD40-5/0 Long. I was really shocked, because I thought the Sumo or Huma would have been better. To get a second opinion, I had my wife sit outside about 20 feet from the bench. I tried all three moderators multiple times, but she kept picking the 0dB as slightly more quiet. I was so disappointed with the Huma, that I returned for a refund.
All three moderators reduced the sound to about the same decibel level. But, the 0dB seemed to have a lower pitch, thus making it sound a little more quiet.
However, the Revere with 0dB is still louder than my Taipan Long .25 with Sumo.
I know you have a .25 caliber Revere, so your results could differ.
