About 12 years ago I was doing a recording with Oscar Peterson and Ray Brown and Jack Renner from Telarc in a recording studio in Toronto called Eastern Sound.
While I was sitting in one studio the owner of the studio came in and asked if I was with Bryston. I said yes... and he said... "please follow me". Gee's I thought what have I screwed up now! He takes me into another studio and there behind a glass enclosure are 6 Bryston amplifiers with green lights a glowing ... which power the main monitoring speakers in that studio. He says to me "how long do you think those amps have been on?" I say - a while I hope without any issues.
He says - "18 years"!
I smile.

Hi James
I remember them well (the Brytons), as a producer in Multi-Image productions back in 82/83 we used Eastern to record the voice overs, I noticed the Brystons and soon after I was off to Long and McQuade to add a 2BLP to my Electronic Music studio.
