Maril...I'd like to make a few points in response to your concern with the "leading edge" issue. I've already indicated I use the Raven One, and like Pani, initally heard what he did. In fact, a short while ago I posted a thread seeking some assistance in acquiring a cartridge with less leading edge and more trailing end information. That was prior to having my monoblock amps restored to their original status after previously having them modified quite a few years ago, newly inserting them with iec capability enabling choice in power cord selection, changing their 12ax7 and EL34 tubes with different brands and making vta adjusments to my TW Acustic 10.5 tonearm. Collectively, these measures enabled me to effectively eliminate the excessive edge issue without even changing my Dynavector XX2 cartridge. Incidentally, I have not used nor do I presently use any mat with the Raven One platter. I also have not modified either the feet or the foundation or stand on which the table rests. So yes, I initially experienced a bit too much leading edge, but was successful in achieving system synergy and overcoming it. Obviously, I cannot speak for others regarding whether they have faced the same issue, and if so, whether they have managed to optimize their systems to their own satisfaction.
