That's a beautiful rack of vintage SILVER FACED Pioneer gear there, Dart! And a reel-2-reel, too! That puts an exquisite finishing touch to the entire stack. Like the others, I was fully expecting you to list HPM-100s as your speaker complement, so the JBL towers came as a bit of a shock. Once you explained the cost of vintage gear in Brazil, your choice was quite understandable.
Just out of curiosity, how did you arrive at your equalizer curve settings? Are the JBLs THAT lacking in low bass and high treble? I would have assumed that the ES90s would have been much closer to "Harman Target Curve" au naturel, requiring only a little massage for room correction. (Interesting article on the Target Curve, room correction, et al here:

Thanks for posting that beautiful gear.
