Sonic Euphoria Passive Preamp Sold
This passive preamp uses autotransformers. Highly rated by stereophile and many other high end audio journals and is said to outperform preamps costing two to three times more. The preamp has 4 inputs and 2 outputs. This is the most neutral and transparent preamp I have ever owned. I recently purchased an integrated amp, thus I don't need a preamp  Asking $750.
