Wahnfried – Silvercore's premium preamplifier is named after Klaus Schulze's pseudonym and Wagner. It is a purist auto-biased push/pull circuit with 2 x 6922 and 2 x 5687. The remote-controlled 96-step volume controller inserts after the nano-crystalline Finemet pure silver input transformers for galvanic isolation and impedance stabilization. There are equivalent output transformers, an external power supply and custom parts like zinc-foil capacitors. There are 5 x XLR inputs, an XLR tape loop and 2 x XLR outputs. Output impedance is 150Ω and the chassis combines Delrin with stainless steel or, optionally, macassar wood. Wahnfried sells for €18'600. Photo by Image Hifi.
