Get an Audio Technica AT-150MLX. It will take you to the next step. It was designed and marketed to be a $500 cartridge, and it typically sells for $400, but you can get it for $259 at lpgear.com or for $250 with free shipping at J&R Music World. It is a magnetic cartridge with a replaceable stylus, which is available from lpgear.com for $179.95, or the price of a DL-160.
I have had both cartridges on my Technics SL1210M5G. The DL160 is a nice cartridge for the money--vivid soundstage, some speed, linearity, and clarity for the money, but for that little bit more for the AT150MLX moves you into a more high end experience--way more detail and clarity, soundstage, frequency extension, and dynamics, both in terms of nuance and jump.
When I was using the DL160, I liked what it gave me but I wanted more. With the AT150MLX I simply enjoy the music and don't think about it. I know that I'd have to spend quite a bit more to get noticeably better.
