I am trying to decide on a cartridge for a Clearaudio Performance. Three of my consideations are Benz Micro Wood vs Shelter 5000 or 7000 vs. Ortofon Kontrapunkt C. My current system cinsists of Innersound Kaya hybrid electrostats, Spectral DMC 12 preamp, and bel canto Ref1000 monoblocks. I am planning on adding a Lyngdorf DPA-1 preamp with Room Perfect processor, and then would need a phono preamp. I might go with a Simaudio Moon Lp5.3 to take advantage of its balanced outputs. Any comments or suggestions?
