There is a substantial gap here in build quality alone Accuphase is far better
made in Japan which has much much more QC as well as parts quality,
also their failure rate in the lowest 5% in the worlld going from others I read over a 20 year period ,in their preamp section a patented volume attenuator,
look at prima luna in the magazines up front left a Round silver can which is a low cost Alps or burns volume pot ,2 pieces of plastic wipers with a conductive spray on them , why ? When a ladder resistor , or relay volume attenuator is far more accurate .
