I have recently added a Supratek to my system. Previously I was running the Wadia at 0.25V output into 750 watt monoblocks. The sound was great but quite dry. To keep the 861 in its sweet spot meant that the volume was either too low (when I really wanted to crank it up) or too high if I changed the dipswitch settings to higher levels. The addition of a tube pre amp has made all the difference. A really smooth, warm engaging sound, the Wadia running at 100% resolution and absolute control over the volume/resolution combination. Check out the thread titled "Pre amp deal of the century" for info on Supratek pre amps. For my system, addition of a pre amp has been wonderful.
