WALKER AUDIO phono stage
Lloyd Walker has designed and built a ss phono stage with Teflon circuit boards which retails for approx. 8K. If his tt is anything to go by, this should be an exceptional item. I hear that it has a low noise floor, specifically where high gain is required (ie for low output cartridges). Has anyone owned or auditioned this piece?
