I just replaced the felt pads under my U4 with sorbothane pads and there is a difference in sound, more 3d, it's like a put a big juicy mullard rectifier in it. What are you guys using for feet on Dr Lloyds components?

I'm using Herbies Audio Labs Tenderfeet, 3 each under the Ultra linestage and power supply.  It provides nice improvement in overall tonality.  Everything I've used from Herbies as been a worthwhile investment (and he offers a money back gurantee so nothing to lose by trying).
