Very good to see another who likes the Signet TK-10, I like(d) it so much I had one of them van den Hul tipped. I always wanted to try varying capacitor loads with it. I have a love-hate relationship with the Koetsus. I had my Urishi for sale but then pulled it after a sale fell through. I've had ProIVs and Rosie Siggis but the older I get the more detail I desire. Of course, next year I'l feel just the opposite. I find that cartridges are like women...
