Lack of bass with mac mini mp3/apple lossless file


My system sounds great with movies, the bass is awesome, but my music file on my mac mini bass is just not there. I have the fist gen macmini and using the optical output to my marantz av8003

Rezanazari, haven't heard from you yet on the first post, are you using your home theater's sub when listening to music? My AVR has settings that will only use the front speakers if I want, I think it is called "standard" or something. I typically use one of the home theater surround settings for two channel music in my HT, I forget which one, but the processing fakes 5.1 out of a 2 channel signal.
Signal processing makes a huge difference when playing two channel on an AVR in a home theater. I had to tweak and tweak and TWEAK to get my Denon AVR to sound as good as a 20 year old Yamaha receiver in 2 channel (front speakers only).
Thanks for all the info guys. When I listen to music, I use my receiver in 2 channel mode with one or 2 of my subs ( I have 3, very large room). I'll look into USB and the Synchro-Mesh
thanks again
