hai, u mention about the S70, it just look like very interested. due to my knowledge on the player, Loudness system, the most of the player should have it & once we activate the system, we can saw the "LD" in the display mode...

This system can be activated anytime weither we use for CD, Cassette or Radio. I still have no idea about the ASC purpose, and look like very funny when u said the system to increase the volume by the car speeding control.

one more thing about the "dolby" only can activated once we use the cassette player due to the system can reduce unnecessary noisy but not to increase the quality sound. And this system may to auto reduce the treble/tweeter sound performance. Am I right !!

anyway, thanks to your information to me. now, i beleive the Volvo Player have no include the Loudness system... Than, I need to install amplifier to increase the sound quality performance..
