I too have both the Supratek Chardonnay, latest version, and the latest Sachs. Both sound great but like datman said slightly different presentation. Supratek has more functional flexibility in terms of inputs/outputs, gain adjustment and balance while the Sachs has more remote control capability. You can buy the Supratek new for $2000 plus the shipping. The Sachs is fussier about the quality of the two input tubes.
