I currently have a Technics SL-D2 direct drive turntable with a Ortofon cartridge I paid about $69 for at The Neddle Doctor I forget the model, connected to my Denon AVR-1906 receiver through an old Marantz integrated I'm using as a phono stage. My speakers are B&W DM220s. It is a humble set up but it serves me well. The Marantz is being moved to another room for other duties and I am planing on investing about $500 into my playback system. My question is would I be best served spending the entire $500 on a phono stage or should I also replace the cartridge, or should I just get a whole new turntable? Any suggestions are welcome. Just don't tell me to replace the receiver because it is in my living room and is my main HT system.
