I am very sad to hear this. I visited Paul at his house in Whitstable a few times and he was always a delight to be with and discuss things especially loudspeaker technology. He always had time for me and what I was doing at the time. I remember back in 2015 at Air Studios in London we talked a lot in the control room about the record being mastered. The recording session was even featured in Stereophile magazine, thanks to Paul.
RIP Paul, you were a lovely person and will be very sorely missed, especially in Hi-Fi circles. Condolences to his wife and family.
