RC, I owned one in 1985 to run the Koetsu ONYX sapphire I had, going into an ARC Mag phono input. While I assumed it would be the step up of choice, the Cotter, beat it in the Mk IIL version. I later purchased a preamp with enough gain, and that beat all of the boxes I had on hand (including the highly regarded Klyne and ARC MCP-33. Hope this helps.....Frank
