Hi, sorry to see noone else respond to your thread. I am not familar with the Dual model you have but do know they made some good turntables. I would recommend replacing the cartridge first and then get some high quality lps and enjoy. You can find a replacement cartridge at a number of retailers (needle doctor, audio advisor, etc,) You can also go to the audioasylum.com and ask those who are still into analog what they would recommend.
I too recently got back into lps and let me tell you its all I have been buying lately. Take a good turntable like the dual and some high quality lps (MFSL, Nautilus, Direct to Disc, etc.) and the sound is simply better than cd...maybe even SACD or DVD-A (haven't compared). Make sure to get some good record cleaning fluid and brushes (disc doctor, LAST, etc) or a record cleaning machine (VPI) to remove the pops and background noise-what a difference.
