LUCID Posted July 26, 2025 Author Report Posted July 26, 2025 @BriaBbnA thank you for confirming. I found out after several test, the ra670 is clean at max volume. At the time I played my test tones from (Rockford fosgate playlist) on Spotify when setting the gains. I’ve been pretty happy with my system, but I’m starting wonder if I’m leaving juice on the table since tracks on Spotify are compressed? I’m wondering if I should download the test tones from the cd and transfer to my phone and play via Bluetooth or download directly from damore website on to phone and play via Bluetooth? What do you all suggest, for those who don’t use usb aux or cd. Quote

Joe X Posted July 27, 2025 Report Posted July 27, 2025 Spotify uses loudness normalization which definitely defeats the tone levels, 100% use the tones on the CD or the downloaded version to do your tests. Quote
