Thanks lewm for your response.
Somehow, the majority of cartridges I've used so far are Ortofons MC cartridges, including very low output MC20, SL15, SL20, and MC20 super, and SPUs (Gold ref, Silver Meister MKii, and mono). I like them all. But I've never had a chance to try those 4 digit cartridges. Maybe they cost much more than I could afford to, but I just wonder how much better they could be compared to SPUs.
