As you know, you already have a great sounding setup. I know this is true since I have a Galibier Gavia with Triplanar VII and Benz LP and it sounds very nice indeed. Putting aside cartridge issues, which tend to be rather personal, you might want to consider a different tonearm, not that there is anything wrong with the Triplanar but just to try a different type of sound. I recently added an Analog Instruments Siggwan which is a 12" cocobolo arm. It is too early to say how it compares to the Triplanar but the Siggwan is especially easy and fun to listen to.
I am convinced that 12" arms are capable of better tracking. This is my 3rd 12" arm and each one has had cleaner tracking in inner grooves than any of the 9" and 10" arms I've owned. In addition to this sense of ease and composure, the Siggwan is notable for its lack of mechanical colorations. In contrast, the Triplanar has excellent detail but sounds more like a metal or mechanical instrument. It's hard to describe but whatever coloration is responsible for this is missing from the Siggwan.
I see that you have several Doshi pieces so you must like the Doshi sound. I have heard the Doshi gear at RMAF but not in my own system so can't offer any suggestions there.
