It has been over year I came to this forum and couldn't be happier about the equipment I own with recommendations from this forum. Now,it is time to find out what is the weakest link in my equipment and upgrade that link. My upgrade budget is $500. I listen to music and movies 50-50. My current equipment is Denon AVR-1603, Paradigm Titans (Front),CC-170,Atoms(Rear) ,PDR-10 and Sony Trinitron 27". I would appreciate any suggestions as which piece of equipment should I consider to upgrade within my budget.
