Mark III Poseidon Boards and Russian PIO caps
Posted: Wed Jul 24, 2013 6:48 am
Recently, I completed a pair of Mark IIIs using the Poseidon boards and am delighted with the results! I have read a lot about using Russian PIO caps in tube amps, so my question is, would I hear a noticeable improvement in sound quality if I substitute Russian PIO caps for the Orange Drops on these boards?
