I must have watched the Ron Carter special at the same time you did. An excellent presentation and it filled in some gaps for me. It also prompted me to pull out a number of my CDs and LPs featuring Ron Carter and enjoy them all over again. I then found a few other recordings via streaming including what is now one of my favorites—-“Chemistry” with Houston Person.
As far as Ron’s stereo goes, I was a little surprised that he seems to use CDs almost exclusively but I was more than a little surprised he was playing them on a boom box instead of through the nice looking speakers shown in the video. I later found out they are Tetra 606 speakers which sold in the $30K range. Not too shabby! I’ve never heard the Tetras but I bet Ron’s bass sounds great on them.
