I've been looking into this cartridge and have been fascinated by its uniqueness and the myriad necessary set up parameters to dial it in. I've spoken to Warren who gave me the thumbs up after a little light grilling to try a super gold. I've not pulled the trigger as loading is not something I can change with my phono set at 47k and I'm hesitant to jump until my pre allows for this. Curiously, The issue of resistance loading of my preamp did not come up with Warren only arm and set up experience. It was not something I was aware of on my part and thought to ask about at that time.
One other question/concern I have after reading this great thread is does the lack of soundstage width that Halcro mentions twice above consistent with other users experience?
