Bob Latino and Roy Mottram,I don't care for the choice of the blue metal oxide resistors used in many places.Notice the resistors I used on this particular board and this actually actually removes most that sterile sound you are experiencing in an otherwise very fine amp.Also,you may want to try a different paper in oil cap like a vitamin Q or Pyramid,as opposed to the K40y feeding the interim stages.
