Hi there, ok I have the N/Y small stone re issue having owned one in the 70’s. All I can say is get it while you can because I understand it is to be discontinued. This percieved volume drop I personally think is rubbish. If you think about the sound spectrum and the phaser is sweeping it so it is picking out a ‘part’ of that spectrum as it moves, so you are not getting the whole picture so to speak. But you are getting the relative volume. Its personal taste I know but I would go for the N/Y small stone every-time.
