Before dismantling system and or getting a sub couple things I found helpful.I was came to understand the dynamics of sound,Vibrations.Isolate the components.The bass you long to hear,Its there on the recording.I know, quality of recordings,not all the same,but the poor sound you hear or dont hear assume the recording is good,the question wheres the bass,Its there,Put on some headphones youll hear the bass,then just start working backwards to check quality of cabling.I an totally a bass man.all my life .The sub in previous system,I could shake the close neighbors windows@ 2,3 in the morning.I,m in a large room,great sounding speakers,And no sub.I hear the bass guitar as it goes through each note,its easy to imagine ,close my eyes.I,m there,Never listened to bob dylan before .His voice hurt my ears.I listened for the 1st time on good equipment.I played it 3 times yesterday at a high volume& I,m still shocked ,his voice is alright. try some free DIY tweeks before buying anything else.Good Luck
