The Benz Lo4 beats the AT OC-9. You could relax much better with it, double sheesh...And if I had to buy one with cost not being an object, I'd buy the Koetsu Onyx Platinum, whether I compared it directly with others in my system first, or not. Besides tracking force, VTA and preamp loading/gain can certainly fine tune the cartridge to synergize with the sound of the rest of your system...no doubt about that.
